Development of regio- and stereoselective dehydrogenative silylation and hydrosilylation of vinylarenes with alkoxysilanes, catalyzed by ruthenium alkylidenes, is described. Varying L- and X-type ligands on ruthenium alkylidenes permits selective access to either (E)-vinylsilanes or β-alkylsilanes with high regio- and stereocontrol. cis,cis-1,5-Cyclooctadiene was identified as the most effective sacrificial
描述了由烷基亚烷基钌催化的乙烯基芳烃的区域和立体选择性脱氢甲硅烷基化和氢化硅烷化的发展。钌亚烷基上的不同L型和X型配体允许选择性控制具有高度区域和立体控制的(E)-乙烯基硅烷或β-烷基硅烷。顺式,顺式-1,5-环辛二烯被认为是乙烯基芳烃脱氢甲硅烷基化的最有效的牺牲氢受体,可以使用几乎等摩尔比的烯烃和硅烷。
