A simple access to transition metal cyclopropenylidene complexes†
Abstract
We report the first example of BAC–Cu complex (BAC = bis(diisopropylamino)cyclopropenylidene) and its use as a carbene-transfer reagent, allowing access to Au–, Pd–, Ir– and Rh–BAC compounds. Catalytic experiments show the high activity of the [CuCl(BAC)] complex in Click chemistry.
