Heteroaryl ethers by oxidative palladium catalysis of pyridotriazol-1-yloxy pyrimidines with arylboronic acids was written by Bardhan, Sujata;Wacharasindhu, Sumrit;Wan, Zhao-Kui;Mansour, Tarek S.. And the article was included in Organic Letters in 2009.Formula: C17H27F6N7OP2 The following contents are mentioned in the article:

The oxidative palladium-catalyzed cross-coupling of pyrimidines containing pyridotriazol-1-yloxy (OPt) as either a urea or an amide functional group with arylboronic acids in the presence of Cs₂CO₃ in DME containing 0.6-1.0% H₂O is described for the preparation of heteroaryl ethers. The bromo substitution in the case of 3-(5-bromo-pyrimidin-2-yloxy)-3H-[1,2,3]triazolo[4,5-b]pyridine could serve as a handle for further elaborations such as Suzuki coupling for attaching varied aryl groups. This study involved multiple reactions and reactants, such as ((3H-[1,2,3]Triazolo[4,5-b]pyridin-3-yl)oxy)tri(pyrrolidin-1-yl)phosphonium hexafluorophosphate(V) (cas: 156311-83-0Formula: C17H27F6N7OP2).

However, triazoles are also useful in bioorthogonal chemistry, because the large number of nitrogen atoms causes triazoles to react similar to azides.Triazole heterocyclic structures are found to form many weak nonbond interactions with the receptors and enzymes in biological systems.Formula: C17H27F6N7OP2

Redox-gated electron transport in electrically wired ferrocene molecules was written by Xiao, Xiaoyin;Brune, Daniel;He, Jin;Lindsay, Stuart;Gorman, Christopher B.;Tao, Nongjian. And the article was included in Chemical Physics in 2006.Formula: C17H27F6N7OP2 The following contents are mentioned in the article:

We have synthesized cysteamine-terminated ferrocene mols. and determined the dependence of the electron transport properties of the mols. on their redox states by measuring the current through the mols. as a function of the electrode potential. The current fluctuates over a large range, but its average value increases with the potential. We attribute the current fluctuation and its increase with the potential to the switching of the mols. from low-conductance reduced state to high-conductance oxidized state. This study involved multiple reactions and reactants, such as ((3H-[1,2,3]Triazolo[4,5-b]pyridin-3-yl)oxy)tri(pyrrolidin-1-yl)phosphonium hexafluorophosphate(V) (cas: 156311-83-0Formula: C17H27F6N7OP2).

The triazole ring is a relatively stable functional group, and the triazole bond can be used for a variety of applications, such as replacing the phosphate backbone of DNA. 1,2,3-Triazoles are usually prepared following (3+2) cycloaddition protocols. A common technique for unsubstituted triazoles is the Huisgen azide-alkyne 1,3-dipolar cycloaddition: a azide and an alkyne react at high temperature to form a ring. However, the Huisgen strategy produces a mixture of isomers (typically 1,4- and 1,5-disubstituted) when used to produce substituted triazoles.Formula: C17H27F6N7OP2

Pyrrolidide formation as a side reaction during activation of carboxylic acids by phosphonium salt coupling reagents was written by Alsina, Jordi;Barany, George;Albericio, Fernando;Kates, Steven A.. And the article was included in Letters in Peptide Science in 1999.SDS of cas: 156311-83-0 The following contents are mentioned in the article:

Pyrrolidide derivatives are observed as unwanted byproducts from slow reactions of activated carboxylates with nucleophilic amines, as mediated by phosphonium salt coupling reagents (PyAOP, PyBOP, PyBroP). This side reaction is attributed to the presence of small amounts (e.g., 0.5%, weight/weight) of pyrrolidine as a contaminant to com. phosphonium salts, and does not occur when the reagents are crystallized before their use in coupling reactions. This study involved multiple reactions and reactants, such as ((3H-[1,2,3]Triazolo[4,5-b]pyridin-3-yl)oxy)tri(pyrrolidin-1-yl)phosphonium hexafluorophosphate(V) (cas: 156311-83-0SDS of cas: 156311-83-0).

On the use of PyAOP, a phosphonium salt derived from HOAt, in solid-phase peptide synthesis was written by Albericio, Fernando;Cases, Marta;Alsina, Jordi;Triolo, Salvatore A.;Carpino, Louis A.;Kates, Steven A.. And the article was included in Tetrahedron Letters in 1997.Application of 156311-83-0 The following contents are mentioned in the article:

Phosphonium derivatives of HOAt such as PyAOP (I) are useful for the solid-phase preparation of a range of peptides that include those incorporating hindered amino acids, difficult short sequences, and cyclic peptides. An advantage relative to uronium salts is that excess PyAOP does not undergo the detrimental side-reaction at the amino terminus which blocks further chain assembly. This study involved multiple reactions and reactants, such as ((3H-[1,2,3]Triazolo[4,5-b]pyridin-3-yl)oxy)tri(pyrrolidin-1-yl)phosphonium hexafluorophosphate(V) (cas: 156311-83-0Application of 156311-83-0).
