The turnover number could amount to 925when reacted for 42 h without deactivation of the catalyst.展开更多
Hydroformylation of methyl methacrylate with a coneversion of 95.6% and selectivity of 92.8%for the normal product. methyl γ-formylisobutyrate has been achieved when the reactien was catalyzed by a silica-supported P...Hydroformylation of methyl methacrylate with a coneversion of 95.6% and selectivity of 92.8%for the normal product. methyl γ-formylisobutyrate has been achieved when the reactien was catalyzed by a silica-supported Poly-γ-aminopropylsiloxane-rhodium-cobalt bimetallic complex (abbreviated as SiO2- NH2-Rh-Co). The catalyst was Stable during the reaction and could be used repeatedly.展开更多
