The Synthesis of Some Perhydrobenzimidazolinium Salts and Their Application In Pd-Carbene Catalyzed Heck And Suzuki Reactions

Abstract

Novel 1,3-dialkylperhydrobenzimidazolinium chloride salts were prepared as precursors of N-heterocyclic carbenes 3a-e by reacting N,N'-dialkylcyclohexandiamine, triethyl orthoformate and ammonium chloride. The salts were characterized spectroscopically and the complexes formed in situ from Pd(OAc)(2) and 3 have been tested as catalysts in homogenous Heck and Suzuki reactions.
