Metal Carbonyl Complexes of Sapphyrins

Abstract

Mono- and binuclear Rh and Ir complexes are easily obtained by reaction of sapphyrins with [{RhCl(CO)2}2] and/or [IrCl(CO)2(py)]. In these binuclear complexes (e.g., 1), the two [M(CO)2] fragments are no different sides of the ruffled 22 π-electron ligands. Complex 1 catayzes the hydrogenation of cyclohexenes.
