[RuCl(2)(p-cymene)](2) as a catalyst, extremely high regio- and stereoselectivity was observed in the hydrosilylation reaction of various terminal alkynes under mild conditions to afford beta-(Z)-vinylsilanes in excellent yields. A dramatic directing effect was also observed when alkynes having a hydroxyl group at the beta position to the triple bond were employed as a substrate, and in these cases regioisomeric
以[RuCl(2)(p-cymene)](2)作为催化剂,在温和条件下,各种末端
炔烃的氢化
硅烷化反应中观察到极高的区域选择性和立体选择性,从而以极高的收率得到β-(Z)-
乙烯基硅烷。当使用在三键的β位具有羟基的
炔烃作为底物时,也观察到了引人注目的指导作用,在这些情况下,以优异的选择性产生了区域异构的α-
乙烯基硅烷。
