The effect of different ancillary ligands and counterions in platinum(II) complexes has been investigated. Based on the previously reported tridentate C<^>N<^>N ligand precursor 2-(1-benzyl-1H-1,2,3-triazol-4-yl)-6-phenylpyridine (HL), the photophysical properties of complexes of the type [Pt(L)(X)](n+) have been varied by changing the fourth (monodentate) ligand (X) of the square-planar platinum(II) complexes. Different lifetimes and quantum yields were observed, depending on the identity of this ancillary ligand. The most favorable photophysical properties within this series of complexes were obtained for neutral complexes with the phenylacetylido ligand with a quantum yield of 35% and a lifetime of 2.22 mu s, while for cationic complexes bearing nitrile, isonitrile and triphenylphosphane units gave comparable results with quantum yields ranging from 11% to 16% and lifetimes from 3.59 mu s to 4.93 mu s. Introducing a ferrocene moiety attached to an acetylido ligand, the complex became hardly emissive. The investigated counterions perchlorate, tetrafluoroborate and hexafluorophosphate of positively charged complexes regarding their photophysical properties were found to affect the non-radiative decay rates. To understand the minor effect observed for the emission maxima of the complexes, density functional theory (DFT) was applied. The experimental emission spectra of the complexes were reproduced by using simplified model systems. The distribution of the frontier orbitals used for the description of the emissive T-1 state in its optimized geometry mainly involves the tridentate luminophore rather than the ancillary ligand. This explains why the emission is dominated by the pincer unit with perturbative participation of the metal center while excluding significant influence of the ancillary ligand.

Haloalkenyl Imidoyl Halides as Multifacial Substrates in the Stereoselective Synthesis of N-Alkenyl Compounds

N-Alkenyl compounds are versatile synthetic building blocks and their stereoselective transformations are key processes in the synthesis of many prominent classes of natural products, pharmaceuticals, and agrochemicals. However, a large structural variety of known N-alkenyl compounds and their diverse reactivity have so far precluded the development of a general method for their stereoselective synthesis. Herein we present an aluminum halide-mediated, highly stereoselective, efficient and scalable transformation of commercially available N-fluoroalkyl-1,2,3-triazoles to N-haloalkenyl imidoyl halides, and demonstrate their use in the synthesis of stereodefined N-alkenyl amides, amidines, imines, hydrazonoamides, imidothioates, iminophosphonates, 1,2,4-triazoles and tetrazoles. The reaction is of wide scope on both the triazole substrate and aluminum halide, providing highly functionalized products. Mechanistic and computational investigations suggest a reaction mechanism involving the triazole ring opening, initiated by the coordination of nitrogen one of the triazole ring to the Lewis acid, N-2 elimination and the formation of a vinyl cation intermediate, which reacts with nitrogen-bound aluminum halide, followed by a series of halide exchange reactions on C-X and Al-X bonds.

1,2,3-Triazole based poly(ionic liquids) as solid dielectric materials

1,2,3-triazole based polyionic liquids (PIL) are an emerging field among polymeric dielectrics in organic electronics. 1,2,3-triazole based PILs can be obtained from poly(4-vinylbenzylchloride) by copper-catalyzed azide-alkyne cycloaddition (CuAAC) ‘click’ reaction. The polymer architecture and the charge of the PILs can be manipulated by choosing a suitable alkyne, azide containing moiety, and by the alkylation of the 1,2,3-triazole group. Thus, we were able to prepare PILs carrying either inorganic (Na+ or Cl-) or the organic counterions 1-butyl-3-methyl-imidazolium (C4mim(+)) or 1-butyl-3-methyl-imidazolium (TFSI-). Metal-insulator-metal capacitors were fabricated and the dielectric properties were characterized through electrochemical impedance spectroscopy. The PILs demonstrated an increase in capacitance density with decreasing frequency, characteristic for the polarization of the polymer layer and electrical double layer formation. Substitution of inorganic counterions with organic counterions improved the transition frequency of the capacitors and the conductivity of the polymers. This was due to increased ion mobility and decreased glass transition temperatures.

Fluorescent Assembles of 2-Amino-3-cyanothiophenes with Azoles. Design and Peculiar Properties of Absorption and Emission

Three new types of azolylthiophene fluorescent dyes, (1-aryl-1H-1,2,3-triazole-4-carbonyl)thiophenes (ATTs), (3-arylisoxazole-4-carbonyl)thiophenes (AITs), 1-aryl-1H-pyrazole-4-carbonyl)thiophenes (APTs), were synthesized by the 1,3-dipolar cycloaddition reaction. All the synthesized luminophores exhibited blue emission with high quantum yields (QYs) and positive solvato(fluoro)chromism. Photophysical investigations established the role of the heterocyclic core, substituents, and their combinations for the azolylthiophenes emission. ATTs and AITs exhibited a decrease in QY in polar solvents, while APTs showed the largest QYs in DMSO and DMF. Solvato(fluoro)chromism was analyzed by using the Lippert-Mataga equation. These results revealed that ATTs are the most sensitive to the environment interactions among the investigated compounds. Azolylthiophenes exhibited intense green emission in the solid state (up to 75.9%). The experimental work was supported by quantum chemical calculations.

Multi-functional, Low Symmetry Pd2L4 Nanocage Libraries**

Although many impressive metallo-supramolecular architectures have been reported, they tend towards high symmetry structures and avoid extraneous functionality to ensure high fidelity in the self-assembly process. This minimalist approach, however, limits the range of accessible structures and thus their potential applications. Herein is described the synthesis of a family of ditopic ligands wherein the ligand scaffolds are both low symmetry and incorporate exohedral functional moieties. Key to this design is the use of Cu-I-catalysed azide-alkyne cycloaddition (CuAAC) chemistry, as the triazole is capable of acting as both a coordinating heterocycle and a tether between the ligand framework and functional unit simultaneously. A common precursor was used to generate ligands with various functionalities, allowing control of electronic properties whilst maintaining the core structure of the resultant cis-Pd2L4 nanocage assemblies. The isostructural nature of the scaffold frameworks enabled formation of combinatorial libraries from the self-assembly of ligand mixtures, generating a statistical mixture of multi-functional, low symmetry architectures.

Carbazolyl-bis(triazole) and Carbazolyl-bis(tetrazole) Complexes of Palladium(II) and Platinum(II)

The synthesis of several carbazole-bis(triazole) (CzTr(R) ) and carbazole-bis(tetrazole) (CzT(R) ) ligands (5a-d and 6a-d, respectively, where R=Me (a), i -Pr (b), Bz (c) and CH2-2,4,6-C6H2Me3 (d)) is reported. Reaction of these ligands with PdCl2 in refluxing acetonitrile affords the complete series of square planar complexes, Pd(CzTr(R))Cl (7a-d) and Pd(CzT(R))Cl (8a-d). The analogous platinum complexes are prepared by deprotonation of ligand carbazole nitrogen under nitrogen followed by reaction with Pt(COD)Cl-2 to give Pt(CzTr(R))Cl (9b, 9d) and Pt(CzT(R))Cl (10b, 10d). The X-ray structure of several ligands (5b, 5c, 6c) and their metal complexes (8b, 8d, 9b) are reported. Complexes 7-10d were examined by cyclic voltammetry and DFT calculations to shed light on their electronic structures. The Pd and Pt complexes of the same ligand (CzTr: 7d, 9d; CzT: 8d, 10d) showed very similar oxidation potentials suggesting the lowest oxidation is ligand based. In contrast, oxidations of the tetrazole complexes 7d and 9d were notably more difficult than the triazole complexes 8d and 10d. Both of these observations are supported by DFT calculations that indicate the HOMO is essentially carbazole pi-bonding in character.

Water-soluble triazole chitin derivative and its based nanoparticles: Synthesis, characterization, catalytic and antibacterial properties

In this work, we treated chitin with 2-(azidomethyl)oxirane and successfully involved the resultant azido chitin derivatives in the ultrasound-assisted Cu(I)-catalyzed azido-alkyne click (CuAAC) reaction with propargylic ester of N,N,N-trimethyl glycine. Thus, we obtained novel water-soluble triazole chitin derivatives. The triazole chitin derivatives and their nanoparticles are characterized by a high in vitro antibacterial activity, which is the same or even higher than that of commercial antibiotics ampicillin and gentamicin. The obtained derivatives are non-toxic. Moreover, the obtained water-soluble polymers are highly efficient green catalysts for the aldol reaction in green solvent water. The catalysts can be easily extracted from the reaction mixture by its precipitation with green solvent ethanol followed by centrifugation and they can be reused at least 10 times.

Redox Instability of Copper(II) Complexes of a Triazine-Based PNP Pincer

The new Cu(I) complex [Cu(PNPNTPh-Ph)Cl] (1) containing the tridentate PNP pincer ligand N,N ‘-bis(diphenylphosphino)-2,6-diamino-4-phenyl-1,3,5-triazine was obtained from the reaction of [Cu(SMe2)Cl](n) with the ligand as ether solvate 1(.)0.5Et(2)O. 1 was independently obtained from a reaction mixture containing the ligand and the Cu(II) precursor CuCl(2)(.)2H(2)O in 50 % yield alongside with the Cu(II) coordination polymer [Cu(O2PPh2)(2)](n) (2). From the reaction of Cu(NO3)(2) . 3H(2)O with PNPNTPh-Ph in the presence of pyridine the complexes [Cu(O2PPh2)(2)(Py)(2)(H2O)] (3), [Cu(O2PPh2)(Py)(2)(NO3)](2) (4), and [Cu(Py)(4)(NO3)(2)]Py-. (5), were obtained, 2, 3, and 4 contain diphenyl-phosphinate ligands. The underlying redox reaction of the ligand and Cu(II) yielding the oxidised ligands observed in the by-products and the Cu(I) product complex was further studied using electrochemistry and UV-vis spectroelectrochemistry. Attempts to synthesise the Cu(II) complex [Cu(PNPNTPh-Ph)(NO3)(2)] (6) in a mechanochemical experiment gave evidence for this unprecedented species from ESI-MS(+) and EPR spectroscopy but also revealed its very high sensitivity to air and moisture. The catalytic activity of 1 was investigated in the azide-alkyne cycloaddition yielding various 1-benzyl-4-phenyl-1H-1,2,3-triazoles.

Copper Supported onto Magnetic Nanoparticles as an Efficient Catalyst for the Synthesis of Triazolobenzodiazepino[7,1-b]quinazolin-11(9H)-ones via Click N-Arylation Reactions

A novel catalyst is designed and synthesized based on immobilization of copper onto modified magnetic nanoparticles. The catalyst was characterized by several characterization techniques. The catalyst was applied for the synthesis of a novel series of heterocyclic scaffold containing a 1,4-benzodiazepine fused with a 1,2,3-triazole ring and a quinazolin-11(9H)-one skeleton. The method is based on the direct synthesis of quinazolin-11(9H)-one ring by the reaction of isatoic anhydride (or anthranilic acid) and propargylamine, and an aldehyde, containing a leaving group on its aromatic ring. The reaction contains an in situ sequential click reaction of azide group with terminal alkyne and subsequent N-arylation reaction to afford the final products. The method benefits various advantages, such as regioselectivity and high yield of the products. The reusability of the catalyst was evaluated and the results showed that the catalyst is highly reusable in 10 sequential reactions.

Anammox enrichment culture has unexpected capabilities to biotransform azole contaminants of emerging concern

Azoles are contaminants of emerging concern. They have a ubiquitous presence in the environment due to their wide variety of uses. This study investigated the fate of two commonly occurring azole compounds in an anammox enrichment culture. The results showed that 1H-pyrazole (PA) and 1H-1,2,4-triazole (TA) were biotransformed yielding major biotransformation products, 3-amino-1H-pyrazole and 3-amino-1H-1,2,4-triazole, respectively. Nitrate and glucose greatly stimulated the biotransformation. Under optimized conditions, 80.7% of PA and 16.4% of TA were biotransformed in an incubation period of 6 days. High molar product yield of 84.5% and 83.6% was observed per mole of PA and TA biotransformed, respectively. This novel and selective biotransformation constitutes the first report on the microbial biotransformation of PA and is amongst the very few reports on the biotransformation of TA. This study also provides evidence that anammox enrichments have unexpected capabilities to biotransform organic contaminants of emerging concern. (C) 2020 Elsevier Ltd. All rights reserved.
