When SiO〓-NH〓-Rh-Co complex was used to catalyze the hydroformylation of methyl methacrylate, an optimal conversion of 93.4% and optimal selectivity of 84.4% for the normal aldehyde were both obtained at Rh/Co ratio of 2/1, which were both higher than that catalyzed by SiO〓-SiNH〓-Rh and SiO〓-Si-NH〓-Co momometallic catalysts. Clearly a synergistic action between Rh and Co atoms presented in the complex.
