(Dicyclopentadiene) platinum(II) dichloride was found to be an efficient hydrosilylation catalyst (homogeneous) upon a wide variety of functionalized alkenes and alkenes terminated with chemical moieties (diphenyl amino-, N-carbazol- and N-isoindoline-1,3-dione-). It is noteworthy that the hydrosilylation of aminated alkenes with triethoxysilane exhibited the yield of over 70% and the selectivity (γ-isomer/β-isomer)
(二环戊二烯)二氯化铂(II)被发现是一种有效的氢化硅烷化催化剂(均相),适用于多种官能化的烯烃和以化学部分(二苯基氨基,N-咔唑-和N-异二氢吲哚-1,3-终止)的烯烃dione-)。值得注意的是,胺化烯烃与三乙氧基硅烷的氢化硅烷化显示出超过70%的收率和超过3/1的选择性(γ-异构体/β-异构体)。由于空间障碍降低了马尔可夫尼科夫概率,具有大末端部分的烯烃(二苯基氨基,N-咔唑-和N-异吲哚啉-1,3-二酮-)呈现出较高的抗马尔可夫尼科异构体比例。开发了保护的二氨基螯合烯烃的氢化硅烷化策略。
