The heterobinuclear metal carbonyl compounds,(dppe) Rh(μCO)2M(CO)3(M=Cr, Mo, W),were synthesized and characterized by elemental analysis, IR and 1H NMR spectroscopic means. The SiO2-supported complexes were used as catalysts for CO hydrogenation and hydroformylation of propene. The catalytic activities and selectivities were determined. The high activity and selectivity of oxygenates for CO hydrogenation are brought about under atmospheric pressure at 240℃. The in situ FT-IR spectra of the complex catalysts...
