以原位形成的膦钌络合物为催化剂, 研究了含氢硅油对酰胺的还原反应, 考察了酰胺的结构、反应溶剂、配体等条件对催化反应的催化效率及产物结构的影响. 仲胺基及伯胺的酰胺化合物被还原成相应的叔胺及仲胺|丙烯酰胺与含氢硅油反应时, 选择性较差, 得到丙烯腈、丙腈及与硅烷基相连的聚丙烯酰胺与聚丙烯腈.

The reduction of amide promoted by “in situ” formed ruthenium phosphine complex was carried out using polymethylhydrosiloxane as reductive reagent. The effects of structure of the amide, solvent and ligand on the catalytic efficiency and the product have been evaluated. The amide with secondary or primary amine group produces to the corresponding tertiary amine and secondary amine. The reaction of acrylamide with polymethylhydrosiloxane is complicated to produce acrylonitrile, propionitrile and polymer with the siloxane-based linked polyacrylamide and polyacrylonitrile.

Key words: polymethylhydrosiloxane, reduction of amide, ruthenium complex, catalytic hydrogenation, preparation of amine
