Abstract

The trinuclear copper(I) pyrazolate {[3,5-(CF3)2Pz]Cu}3 forms η2-copper/alkyne triple bond coordinated structures in the presence of acetylenes. There is no coordination of copper atoms to the phenyl ring of phenylacetylene and copper(I) acetylide formation during the interaction. It was observed that the complexes formed are the active catalytic species in click reactions.
