A process for producing a silylated product comprises reacting a mixture comprising (a) an unsaturated compound containing at least one unsaturated functional group, (b) a silyl hydride containing at least one silylhydride functional group, and (c) a catalyst, optionally in the presence of a solvent, to produce a dehydrogenative silylated product, a hydrosilylated product, or a combination of a dehydrogenative silylated product and a hydrosilylated product, wherein the catalyst is chosen from a pyridine diimine cobalt dicarboxylate complex or a cobalt carboxylate compound, and the process is conducted without pre-activating the catalyst via a reducing agent and/or without an initiator or promoter compound. The present catalysts have been found to be active in the presence of the silyl hydride employed in the silylation reaction.
生产硅烷化产物的方法包括反应一个混合物,该混合物包括(a)至少含有一个不饱和官能团的不饱和化合物,(b)至少含有一个硅烷基官能团的硅氢化物,和(c)催化剂,可选地在溶剂的存在下,以产生脱氢硅烷化产物,氢硅烷化产物,或脱氢硅烷化产物和氢硅烷化产物的组合,其中催化剂选自吡啶二亚胺钴二羧酸盐络合物或钴羧酸盐化合物,且该方法在不通过还原剂预激活催化剂和/或不使用引发剂或促进剂化合物的情况下进行。已发现这些催化剂在硅烷化反应中使用的硅烷化物存在下具有活性。
