Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.We report an efficient method for late‐stage installation of “clickable” alkyne groups into diverse (hetero)arenes. Using a dual‐ligand palladium catalyst that combines an NASA ligand with an N‐heterocycle, an acrylate unit bearing a terminal alkyne can be introduced via nondirected C─H activation.

Monolayer doping of Si with improved oxidation resistance [PDF]
, 2016 In this article, the functionalization of planar silicon with arsenic- and phosphorus-based azides was investigated. Covalently bonded and well-ordered alkyne-terminated monolayers were prepared from a range of commercially available dialkyne precursors ...

1,2,3-Triazoles as Amide-bond Surrogates in Peptidomimetics
CHIMIA, 2013 1,2,3-Triazoles represent a class of heterocycles with interesting properties for application in peptide sciences since they closely resemble amide bonds while being stable to enzymatic degradation. These characteristics make 1,2,3-triazoles promising candidates as amide-bond surrogates for the development of novel peptidomimetics with ...

Ligand synthesis catalyst and complex metal ion: multicomponent synthesis of 1,3-bis(4-phenyl-[1,2,3]triazol-1-yl)-propan-2-ol copper(i) complex and application in copper-catalyzed alkyne-azide cycloaddition [PDF]
, 2016 A new bistriazole copper complex was synthesized by direct treatment of an alkyne, an azide, and CuI as copper salt through in situ ligand formation under a multicomponent reaction process. This complex was analyzed by XPS, TGA, DSC, and SEM techniques
