Abstract

Abstract Cationic rhodium (i) and iridium (i) complexes containing the bidentate heterocyclic N, N-donor ligand bis (1-pyrazolyl) methane (bpm) and the counterion tetrakis [3, 5-bis (trifluoromethyl) phenyl] borate (BArF–) were found to be efficient catalysts for the cyclization of activated and unactivated aminoalkenes. The rates of cyclization were found to be highly dependent upon the size and steric bulk of the substituents at the γ-position of the ...
