A dicopper( i )-dimesoionic carbene complex as a click catalyst: mechanistic implications
Résumé
A dicopper(I) complex comprising a dimesoionic carbene and an acetate-bridge is synthesized and fully characterized. This complex is a potent pre-catalyst for the azide–alkyne cycloaddition reaction. A full kinetic investigation shows a first order in azide and a catalyst order smaller than one due to an equilibrated dimerization of the catalyst.
