nickel-catalyzed direct reaction of allylic alcohols with easily accessible alkenyl boronates has been developed, which provides valuable 1,4-dienes with high regio- and stereoselectivity in good to excellent yields, wide substrate scope, and functional group compatibility. The catalytic system simply consists of Ni(cod)2 as the catalyst and a ligand, without a need for a base and alcohol activator in most
镍催化的烯丙醇与易于获得的烯基硼酸酯的直接反应已被开发出来,该反应可提供有价值的 1,4-二烯,具有高区域选择性和立体选择性,产率良好至优异,底物范围宽,且官能团相容性好。该催化体系仅由作为催化剂的Ni(cod) 2和配体组成,大多数情况下不需要碱和醇活化剂。辅助配体的正确选择对于该反应非常重要。根据烯丙醇和/或烯基硼酸酯的取代模式,使用不同的配体来提高反应效率。
