Copper(I) complexes bearing carbenes beyond classical N-heterocyclic carbenes : synthesis and catalytic activity in “click chemistry”
MetadataShow full item record
The synthesis and characterization of abnormal N-heterocyclic carbene, cyclic (alkyl)(amino)carbene, and mesoionic carbene copper(I) complexes are reported. These organometallic species are obtained via a versatile and inexpensive synthetic pathway using readily available reactants, namely copper oxide and iminium salts. The catalytic activity of this series of complexes was evaluated in the [3+2] cycloaddition of alkynes with azides (CuAAC). Outstanding catalytic properties were observed for the abnormal NHC- and triazolylidene-based copper(I) complexes.
