Abstract: The nucleophilic aromatic substitution reactions of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers, i.e., 1H-1,2,3-triazole and 2H-1,2,3-triazole, have been investigated theor. using DFT/B3LYP calculations employing 6-31G(d,p) basis set in gas phase as well as in solvent phase. The computational studies have supported the formation of transition states via one-step concerted mechanism for the nucleophilic aromatic displacement of nitro groups with 1,2,3-triazoles rather than intermediate formation via two-step addition-elimination mechanism. The amination of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers have revealed regioselectivity of peri-attack despite sterically favorable para-attack. The regioselectivity is attributed to the stabilization of the transition state through intra-mol. hydrogen bond C-H···O=C. This work presents the role of C-H bond as an effective hydrogen bond donor. The mol. interactions through hydrogen bonding have been investigated using AIM method. This work shall result in the synthesis of new regioselective 1,2,3-triazole-derived phthalimide compounds possessing potential biol. candidature.

《Evaluation of N-binding through N1, N2 or N3 of 4-R-1,2,3-Triazolate to [CuCO]+ Complexes》 was written by Franco, Mauricio P.; Carvalho, Beatriz B.; Ribeiro, Marcos A.; Spada, Rene F. K.. Electric Literature of C2H3N3This research focused ontriazole copper complex isomer substituent effect. The article conveys some information:

We computationally investigated eight 4-R-1,2,3-triazolates and their three possible N-binding modes. Optimization of the pre-ligands to verify NPA charges were done with M06-2X/def2-TZVPP. The complexes with [CuCO]+ were optimized with M06 L/def2-TZVPP and the electronic energies were improved with DLPNO-CCSD(T)/cc-pVTZ. Our calculations with pre-ligands indicated the NPA charge of N2 as less neg. than N1 and N3 by at least ∼0.100 e. Taking into account the complexes energies and vibrations, coordination via N2 is the most stable among all three nitrogens in gas-phase by at least, 8 kJ/mol and the vibrational anal. of the νCO indicates linkage isomer N2 as the best electron d. donor among the three linkage isomers. The results exhibit a fine-tuning of ligand donation properties that can be achieved by selecting different R groups in 4-R-1,2,3-triazoles.

《Synthesis of 1,2,3-triazole group-containing isomannide-based aromatic new polyurethanes》 was written by Bayrak, Fatih; Ay, Emriye; Oral, Ayhan; Karayildirim, Tamer; Ay, Kadir. Name: 1H-1,2,3-TriazoleThis research focused ontriazole group isomannide aromatic polyurethane surface property. The article conveys some information:

Ten new carbohydrate-based aromatic polyurethanes have been synthesized using isomannide and/or a new 1,2,3-triazole isomannide derivative, IV, as the diol source in the polymerization reactions. As the isocyanate source, 1,4-phenylene diisocyanate or 2,4-toluene diisocyanate was used. To synthesize compound IV, isomannide was tosylated, the tosyl groups were substituted with azide, the triazole ring was formed by reaction with 2,4-pentane dione and finally carbonyl groups were converted into oximes. The synthesis of copolymers and terpolymers was performed using different proportions of diisocyanate and diol sources in DMF. The structural elucidation of the synthesized compounds and polymers was performed using spectroscopic techniques such as FTIR, 1D- and 2D-NMR and HRMS. The thermal behavior and mol. weight distribution of polymers were analyzed by thermal gravimetric anal. and gel permeation chromatog., resp. The surface properties of the polymers were analyzed using SEM. A comparative study on thermal behavior of the synthesized polymers showed that polymers containing a higher amount of compound IV displayed better thermal stability. The average mol. weights of copolymers were observed to vary from 7,900 (PUR-3) to 21,000 (PUR-4) whereas for terpolymers, values of 19,000 (PUR-5), 5,100 (PUR-6), 22,000 (PUR-8) and 28,000 (PUR-9) were found. The diisocyanate source was found to have more effect on the surface properties of polymers than the diol source: when 2,4-toluene diisocyanate was used in polymer synthesis, the resultant polymers had a spongy morphol. with cavities while a polymer matrix containing spheres and platelets was obtained when 1,4-toluene diisocyanate was used. The results came from multiple reactions, including the reaction of 1H-1,2,3-Triazole(cas: 288-36-8Name: 1H-1,2,3-Triazole)

《Nanobundles of Iron Phosphide Fabricated by Direct Phosphorization of Metal-Organic Frameworks as an Efficient Hydrogen-Evolving Electrocatalyst》 was written by Zhao, Ruo; Gao, Song; Wu, Yingxiao; Liang, Zibin; Zhang, Hao; Xia, Wei; Li, Shuai; Zhao, Yusheng; Zou, Ruqiang. Safety of 1H-1,2,3-Triazole And the article was included in Chemistry – A European Journal in 2020. The article conveys some information:

Transition-metal-based phosphides (TMPs) have been considered as attractive electrocatalysts for water splitting due to their earth-abundance and remarkable catalytic activity. As a representative type of precursors, metal-organic frameworks (MOFs) provide ideal plateaus for the design of nanostructured TMPs. In this work, the hierarchically structured iron phosphide Nanobundles (FeP-500) were fabricated by one-step phosphorization of an iron-based MOF (MET(Fe)) precursor. The derived FeP-500 nanobundles were constructed by quasi-paralleled one-dimensional nanorods with uneven surface, which provided channels for electrolyte penetration, mass transport, and effective exposure of active sites during the water-splitting process. With the addition of conductive Super P, the obtained FeP-500-S exhibited a good electrocatalytic performance towards the hydrogen evolution reaction in alk. electrolyte (1 mol L-1 KOH). Furthermore, to investigate the effect of secondary metal doping, a series of isoreticular MOF precursors and bimetallic TMPs were fabricated. The results indicated that the catalytic performance is structure dominated. After reading the article, we found that the author used 1H-1,2,3-Triazole(cas: 288-36-8Safety of 1H-1,2,3-Triazole)

The article conveys some information:

Hofmann-like cyanometallic complexes represent one of the biggest and well-known classes of FeII spin-crossover compounds In this paper, authors report on the first FeII Hofmann clathrate analogs with unsubstituted 1,2,3-triazole, which exhibit temperature induced spin transition. Two new coordination polymers with the general formula [FeII(1,2,3-triazole)2MII(CN)4] (M = Pt, Pd) undergo abrupt hysteretic spin crossover in the range of 190-225 K as revealed by magnetic susceptibility measurements. Two compounds are isostructural and are built of infinite cyanometallic layers which are supported by 1,2,3-triazole ligands. The thermal hysteresis loop is very stable at different scan rates from 0.5 to 10 K min-1. The compounds display strong thermochromic effect, changing their color from pink in the low-spin state to white in the high-spin state. Their findings show that 1,2,3-triazole is suitable for elaboration of spin-crossover Hofmann clathrate analogs, and its use instead of more classical azines can advantageously expand this family of complexes.
