The first examples of heteroleptic bis-N-heterocyclic carbene (NHC) copper(I) complexes and a mixed NHC–phosphine Cu complex are reported. These complexes are easily synthesized from the reaction of [Cu(OH)(NHC)] with various imidazol(idin)ium or phosphonium tetrafluoroborate salts. These cationic heteroleptic bis-NHC Cu complexes are highly active systems for the azide–alkyne cycloaddition leading

The effect of long‐alkyl‐chain amines in CuI‐assisted azide–alkyne cycloadditions of terminal alkynes with organic azides in glycerol and other environmentally benign solvents (water, ethanol) has been examined. The presence of these additives favors the in situ formation of CuI‐based nanoparticles and results in an increase of the catalytic reactivity. In glycerol, liquid‐phase transmission electron

A new tris(1-benzyl-1H-1,2,3-triazol-4-yl)methanol ligand 3 has been prepared by a triple Cu(I)-catalyzed alkyne-azide 1,3-dipolar cycloaddition (CuAAC). Ligand 3 forms a stable complex with CuCl, which catalyzes the Huisgen 1,3-dipolar cycloaddition on water or under neat conditions. Low catalyst loadings, short reaction times at room temperature, and compatibility with free amino groups make 3-CuCl an outstanding catalyst for CuAAC.
