  Chemoselective hydrosilylation of functionalized alkenes is difficult to achieve using base‐metal catalysts. Reported herein is that well‐defined bis(amino)amide nickel pincer complexes are efficient catalysts for anti‐Markovnikov hydrosilylation of terminal alkenes with turnover frequencies of up to 83 000 per hour and turnover numbers of up to 10 000. Alkenes containing amino, ester, amido, ketone

  使用贱金属催化剂很难实现官能化烯烃的化学选择性氢化硅烷化。本文报道的是定义明确的双（氨基）酰胺镍钳形配合物，是高效的末端链烷烃抗马尔科夫尼科夫氢化硅烷化的催化剂，其周转频率高达每小时83000次，周转次数高达1万次。含氨基，酯的烯烃，酰胺基，酮和甲酰基被选择性氢化硅烷化。反应条件的轻微改变允许使用这些镍催化剂的内部烯烃进行串联异构化/氢化硅烷化反应。

  A series of (salicylaldiminato)methylnickel complexes efficiently catalyse hydrosilylation of various olefins. The complexes are highly active for secondary hydrosilanes and exhibit excellent selectivity for monohydrosilylation. A possible mechanism, which includes a silylnickel complex as a key active species, is proposed.

• Hydrosilylation of Olefins Catalyzed by Iron Complexes Bearing Ketimine-Type Iminobipyridine Ligands

  日期：2017.5.8

  A series of NNN-pincer iron complexes bearing ketimine-type iminobipyridene (BPI) ligands were prepared.. These iron complexes were effective catalysts for the hydrosilylation of olefins using primary, secondary, and tertiary silanes. The effect of the substituents on the imino carbon on the catalytic activity was examined, and it was found that an appropriate combination of the imino carbon and imino nitrogen substituents led to complexes with quite high catalytic activity: the turnover number achieved was up to 42000. These iron catalytic systems provide a low-cost and promising alternative to currently employed precious metal systems for the hydrosilylation of olefins.
