the development of a well-defined Fe catalyst and its application to the regio- and stereoselective 1,4-hydrosilylation of 1,3-dienes. To the best of our knowledge, this is the first example of accessing a characterized low-valent Fe catalyst by controlled reductiveelimination from a readily accessible Fe precatalyst.
我们报告了明确定义的 Fe 催化剂的开发及其在 1,3-二烯的区域选择性和立体选择性 1,4-氢化硅烷化中的应用。据我们所知,这是第一个通过从易于获得的 Fe 预催化剂中受控还原消除来获得表征低价 Fe 催化剂的例子。
Bis(acetylacetonato)Ni(II)/NaBHEt3-catalyzed hydrosilylation of 1,3-dienes, alkenes and alkynes
5-heptanedionato)nickel(II) (1c) as versatile hydrosilylation catalyst precursors is described. Complexes 1a-c catalyze 1,4-selectivehydrosilylation of 1,3-dienes in the presence of NaBHEt3 at ambient temperature. The reactions exhibit good regioselectivity to give the branched isomers as major products. The catalytic system also catalyzes hydrosilylation of alkenes including industriary important siloxy-
