Synthesis of 1,2,3-triazole functionalized hyperbranched poly(ethyleneimine) and its use as multifunctional anionic macroinitiator for diglycidyl ether of bisphenol A curing [PDF]
, 2016 Hyperbranched poly(ethyleneimine) (PEI) has been modified by the addition of propargyl acrylate following a Michael addition reaction. On this polymer (PEI-yne) a copper (I)-catalyzed azide alkyne cycloaddition (CuAAC) has been performed to obtain a ...

ZrCl4-catalyzed C-O bond to C-N bond formation: synthesis of 1,2,3-triazoles and their biological evaluation [PDF]
, 2014 A simple and efficient protocol was developed for the synthesis of aryl azides directly from aryl carbinols using ZrCl4as a Lewis acid catalyst. The azides were converted to novel triazoles under click reaction conditions, which were evaluated for their ...

Methyl 1H-1,2,3-triazole-4-carboxylate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2009 The title compound, C(4)H(5)N(3)O(2), features an essentially planar mol-ecule (r.m.s. deviation for all non-H atoms = 0.013 Å). The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds and π-π stacking inter-actions (centroid-centroid distance 3.882 Å).

Transformations of 1-(Oxiranylmethyl)-1,2,3-triazoles into 2-(Oxiranylmethyl)-1,2,3-triazoles and Alkanenitriles [PDF]
Transformations of 1-(Oxiranylmethyl)-1,2,3-triazoles into 2-(Oxiranylmethyl)-1,2,3-triazoles and Alkanenitriles, 2012 New reactions for the transformation of 1-(oxiranylmethyl)-1,2,3-triazoles into 2-(oxiranylmethyl)-1,2,3-triazoles or alkanenitriles were established. Successive treatment of the substrate with triflic acid and t-BuOH afforded 4,6-dihydro-5-hydroxy-1,3a,6a-triazapentalene derivative.
