硅氢加成是有机硅化学中的重要反应,多种过渡金属包括铁、铑、钌、钯、铂等的配合物对不饱和化合物的硅氢加成均有高的催化活性,尤其在羰基化合物的硅氢化反应中应用广泛.由于有机硅烷可以为包含一个Si—H键的叔硅烷、二个Si—H键的仲硅烷或三个Si—H键的伯硅烷,羰基化合物的硅氢化产物会随硅烷和过渡金属配合物的不同而出现差异.指出了羰基化合物硅氢加成反应的几种机理及其在不同金属配合物和硅烷参与反应时的适用性.重点讨论了Rh,Ru,Fe,Ir反应机理类型和影响条件.此外,描述了部分主要中间体和过渡态以及相关的能量参数,并对第VIII族过渡金属配合物催化羰基化合物硅氢化反应机理的研究进行了展望. Hydrosilylation is an important reaction in organosilicon chemistry. A variety of transition metals, including complexes of iron, rhodium, ruthenium, palladium and platinum, have high catalytic activity for the hydrosilylation of unsaturated compounds, especially in the carbonyl Compounds are widely used in the hydrosilation reaction since the organosilane can be a tertiary silane comprising one Si-H bond, a secondary silane having two Si-H bonds or a primary silane having three Si-H bonds, a hydrosilylation product of a carbonyl compound Which will vary with the silane and transition metal complexes.It is pointed out that several mechanisms of hydrosilylation of carbonyl compounds and their applicability in the reaction of different metal complexes and silanes are pointed out.It is mainly discussed that Rh, Ru, Fe, Ir reaction mechanism types and conditions.In addition, some of the main intermediates and transition states as well as the related energy parameters were described, and the research on catalytic hydrogenation reaction of carbonyl compounds of Group VIII transition metal complexes was prospected.
