starting materials. In this field, the intermolecular regiodivergent 1,2-difunctionalization of alkenes with two electrophiles is still a challenging task. A ligand-controlled, nickel-catalyzed regiodivergent dicarbofunctionalization of alkenes using both aryl/vinyl halides and acetals as electrophiles under mild reductive reaction conditions has been accomplished. This study provides a general approach
区域发散催化为从相同的起始材料构建结构不同的分子提供了一种有效的战略方法。在该领域,烯烃与两个亲电子试剂的分子间区域发散 1,2-双官能化仍然是一项具有挑战性的任务。在温和的还原反应条件下,使用芳基/乙烯基卤化物和缩醛作为亲电子试剂,实现了配体控制的、镍催化的烯烃区域发散二碳官能化。本研究提供了一种从容易获得的丙烯酸酯、芳基卤化物和缩醛中获取 β-甲氧基酯和 γ-甲氧基酯的通用方法。实验机制证据支持区域选择性结果的差异归因于配体调节镍催化剂的反应性,
