Synthesis and transition metal chemistry of ‘phosphomide’ ligands: a comparison of the reactivity and electronic properties of diphenyl-P-perfluoro-octanoyl-phosphine, P-acetyl-diphenylphosphine and P-anisoyl-diphenylphosphine. X-ray crystal structure of [RhCp*(Ph2PC(O)CH3)Cl2]

chloride was found to be a highly unstable, electron poor π-acceptor ligand. The crystal structure of [RhCp*Cl2Ph2PC(O)CH3}] showed a normal pseudo-octahedral piano-stool molecular geometry with a RhP bond length of 2.3186(5) Å. The extra stability observed for the P-anisoyl phosphomides has led us to apply this class of ligand in rhodium catalysed hydroformylation for the first time.
