Abstract

Highly regio-, diastereo- and enantioselective iron-catalyzed sequential hydrosilylation of o-alk-n-enyl-phenyl silanes with alkynes is reported for various 5-, 6-, and 7-membered benzosilacycles in 60-94% yields with up to 95:5 rr, 95:5 dr, and 99% ee. Chiral fully carbon-substituted silicon-stereogenic benzosilacycles could also be obtained via triple hydrosilylation reactions. The unique electronic effect of ligands is observed while adjusting the regioselectivity and enantioselectivity in hydrosilylation reactions. A possible mechanism has been proposed by variable time normalization analysis (VTNA) and H/D exchange experiment.

铁催化的顺序硅氢化反应

高区域，非映对和对映选择性铁催化的邻烷基-正炔-苯基硅烷与炔的顺序硅氢化反应报道了各种5-，6-和7元苯硅环在60-94%的收率高达95:5 rr， 95:5 dr和99% ee。手性全碳取代硅立体苯并硅环也可以通过三次硅氢化反应得到。在调节硅氢化反应的区域选择性和对映选择性时，观察到配体独特的电子效应。通过变时间归一化分析（VTNA）和H/D交换实验，提出了一种可能的机理。
