A study of the rhodium(1)- and iridium(1)-catalyzed hydroboration of olefins with catecholborane is described. Applications to organic synthesis were one focus of this investigation. The scope of the reaction was defined, and issues of stereoselection were addressed. The rhodium-catalyzed hydroboration of several classes of allylic alcohols was found to be highly diastereoselective, preferentially
描述了铑 (1)-和铱 (1)-催化烯烃与儿茶酚硼烷硼氢化的研究。有机合成的应用是这项研究的重点之一。定义了反应的范围,并解决了立体选择问题。发现几类烯丙醇的铑催化硼氢化反应具有高度的非对映选择性,优先提供与未催化反应变体 (9-BBN) 提供的异构体互补的异构体。开发了实现定向烯烃硼氢化的前两种通用方法。亚膦酸盐和酰胺都证明能够传递过渡金属试剂。
