用水溶性钌簇合物Ru3(CO)9(dPPs)3(dPPs=Ph2P—m—C6H4SO3Na,下同)为催化剂,考察了α,β-不饱和酸、苯乙烯、苯乙酮、苯甲醛和环己酮等的加氢反应。发现了题示簇合物[Ru3(CO)9(dPps)3]是催化上述含官能团烯烃的选择氢化的有效催化剂。在甲醇溶液中,该簇合物也有效地催化乙烯羰化生成丙酸甲酯和二乙酮。添加几种卤化物不仅提高了催化活性,而且改变了产物分布。根据催化剂的IR和XPS分析结果,讨论了可能的催化活性物种。
The water-soluble ruthenium clusters Ru3 (CO) 9 (dPPs) 3 (dPPs = Ph2P-m-C6H4SO3Na, the same below) were used as catalysts to investigate the effects of α, β- unsaturated acids, styrene, acetophenone, Cyclohexanone and other hydrogenation reaction. The title cluster [Ru3 (CO) 9 (dPps) 3] was found to be an effective catalyst for the selective hydrogenation of the above functional group containing olefins. In methanol solution, the cluster also catalyzes the carbonylation of ethylene to methyl propionate and diethyl ketone. Addition of several halides not only increases the catalytic activity but also changes the product distribution. Based on the IR and XPS analysis of the catalyst, the possible catalytically active species are discussed.
