Synthesis of a Rhodium Carbonyl Phosphaalkenyl–Phosphido Complex: A Phosphorus Congener of Schiff Base Type N,N′-Chelating Monoanionic Ligands

A monoanionic, bidentate phosphaalkenyl–phosphido ligand was designed, synthesized, and used for the complexation of a rhodium carbonyl fragment. The characterization of the latter revealed delocalized π electrons on the phosphaalkenyl–phosphide moiety. The catalytic activity of this rhodium carbonyl complex has been demonstrated in a hydrosilylation reaction.
