A facile and user-friendly protocol has been developed for the selective synthesis of E-vinyl silanes derived from propargylic alcohols using a PtCl2/XPhos catalyst system. The reaction is generally high yielding and provides a single regioisomer at the β-position with E-alkene geometry. The reaction is extremely tolerant of functionality and has a wide scope of reactivity both in terms of alkynes
已经开发了一种简便且用户友好的协议,用于使用PtCl 2 / XPhos催化剂系统选择性合成衍生自炔丙醇的E-乙烯基硅烷。该反应通常是高产率的,并且在具有E-烯烃几何构型的β-位提供单一的区域异构体。该反应对功能性极宽容,并且在所用炔烃和硅烷方面都具有广泛的反应性。已经研究了催化剂的负载量,发现在极低的催化剂负载量下观察到良好的反应性。这种方法也已扩展到丹麦-Hiyama一锅加氢硅烷化反应。
