A new heterobimetallic palladium–[60]fullerene complex with bidentate bis-1,1′-[P]2-ferrocene ligand

A new heterobimetallic palladium–[60]fullerene complex with ferrocene bis-phosphine ligand was prepared using alternative paths: either via addition reaction of Pd2(dba)3·C6H6 (dba=dibenzylidenacetone) in the presence of 1,1′-bis(diphenylphosphino)ferrocene (dppf) to C60, or via electrochemical activation of C60 to generate C602− anions, which then react with PdCl2 and dppf to yield the target complex. The obtained (η2-C60)Pd(dppf) complex was characterized by 1H- and 31P-{1H}-NMR and electronic spectroscopy as well as electrochemically.
