yielding unactivated terminal olefins vital in organic synthesis. Achieved through ligand control, the reaction exhibits remarkable regioselectivity and suppresses undesired side reactions, particularly 1,5-hydrogen atom transfer (HAT). The process favors primary alkyl halides while preserving secondary and tertiary alkyl bromides, thereby enabling the incorporation of terminal olefins in complex molecules
提出了一种高效方法,用于可见光诱导区域和化学选择性消除卤代烷,产生有机合成中至关重要的未活化末端烯烃。通过配体控制实现,该反应表现出显着的区域选择性,并抑制不需要的副反应,特别是 1,5-氢原子转移 (HAT)。该工艺有利于伯烷基卤化物,同时保留仲烷基溴和叔烷基溴,从而能够将末端烯烃掺入复杂分子中以进行后期官能化。
