N,N'-diferrocenyl-N-heterocyclic carbenes and their derivatives
In continuation of our work on Wanzlick/Arduengo carbenes containing redox-active ferrocenyl substituants we report on the synthesis of N,N'-diferrocenyl imidazol(in)ium salts as precursors of imidazol(in)-2-ylidenes. The necessary starting material for t
