with alkynyl trifluoroborates is described, proceeding through a cobalt hydride-mediated radical-polar crossover metal hydrogen-atom-transfer process. This method affords structurally diverse alkynyl-containing compounds in high yields under mild conditions and features a wide substrate scope, good functional group tolerance, and suitability for late-stage functionalization of relatively complex natural
描述了钴催化的烯烃与三氟硼酸炔基的加氢炔基化反应,通过氢化钴介导的自由基极性交叉金属氢原子转移过程进行。该方法在温和条件下以高产率提供结构多样的含炔基化合物,具有底物范围广、官能团耐受性良好、适合相对复杂的天然产物和生物活性分子的后期功能化的特点。将范围扩大到烯基三氟硼酸盐进一步增加了所开发方法的实用性。这种方法为烯烃与亲核炔基/烯基试剂的自由基参与的炔基化和烯基化反应开辟了一条替代途径。
