A hydroalkynylation reaction of 1,3-dienes with simple alkynes, facilitated by an efficient nickel catalyst system with the 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (Xantphos) ligand, is presented. This reaction displays a broad substrate range for alkynes, encompassing both aryl alkynes and alkyl alkynes, thereby overcoming previous constraints in 1,3-diene hydroalkynylation. The method offers
介绍了 1,3-二烯与简单炔烃的加氢炔基化反应,该反应由有效的镍催化剂体系和 9,9-二甲基-4,5-双(二苯基膦)呫吨 (Xantphos) 配体促进。该反应显示了广泛的炔烃底物范围,包括芳基炔烃和烷基炔烃,从而克服了之前 1,3-二烯加氢炔基化中的限制。该方法为获得高原子和步骤经济性的烯丙基炔烃提供了一种方便、直接的手段。
