methods. It was found to catalyze efficiently the CuAAC reaction for the regioselective synthesis of 1,4-disubstituted-1,2,3-triazoles from benzyl halides, phenylacetylenes, and sodium azide in the presence of sodium ascorbate in water to give the corresponding products under mild and environmentally benign conditions. Various benzyl halides containing electron-withdrawing groups and electron-donating
A series of N‐heterocyclic copper carbene complexes bearing sulfoxide and sulfone moieties have been prepared. In case of new copper compounds with sulfone ligand, the solid‐state structures were determined using X‐Ray crystallography. Obtained complexes were investigated as catalysts in such transformations as: 1,3‐dipolar cycloaddition of alkynes and azides (CuAAC), A3 coupling reaction and β‐hydroboration
(EDX), X-ray diffraction (XRD) and inductively coupled plasma (ICP) analysis. The catalytic activity of CuI-CHT was investigated in the [3 + 2] cycloadditionreactions of alkynes and organic azides for the regioselective click of 1,4-disubstituted-1,2,3-triazole derivatives in water at room temperature. The catalytic results indicate that the prepared CuI-CHT catalyst led to a high yield with a regioselective
The synthesis of a family of N-heterocyclic copper carbene complexes bearing sulfur moiety using different copper(I) halides and convenient route procedures have been reported. The solid state structures of presented copper compounds were elucidated using X-Ray crystallography. Next, obtained complexes were examined in various catalytic transformations including 1,3-dipolar cycloaddition of alkynes
