A Silica-Supported Rhodium Hydroformylarion Catalyst: Evidebce for Dinuclear Elimination

Treatment of 3-(4-chlorophenoxy)-1,2-propanediol with MsCl and subsequently with NaPPh2 gave the diphosphine 2, which could be converted to the silylated phosphines 3 and 4 and attached to silica gel.It was determined experimentally that these ligands are distributed randomly on the silica surface.The synthesis of (P2)RhNBD+BF4- (14) and (P2)RhC3H5 (16) (P2 = 4) is described.Both 14 and 16 are precursors of monohydride catalysts for hydroformylation of styrene under mild conditions.When the silica-supported analogue of 14 was used as a catalyst precursor, the rate per rhodium was found to depend on the distribution of the catalyst on the silica surface.The role of dinuclear reductive elimination is discussed.
