Abstract

Abstract : 4-(1 H -Imidazol-1-yl)aniline was transformed into an isocyanide-functionalized imidazolium salt, which was used in the sequential synthesis of heterometallic complexes containing a ditopic isocyanide–NHC ligand for the first time. Abstract : An isocyanide-functionalized imidazole was obtained from 4-(1 H -imidazol-1-yl)aniline by the Ugi method and subsequently transformed into the corresponding imidazolium salt by treatment with MeI. Coordination of the isocyanide residue allowed the synthesis of several transition metal complexes containing a peripheral imidazolium cation, which are suitable starting materials for the formation of mixed ligand isocyanide–NHC heterometallic complexes.
