A NiH‐catalyzed migratory hydroalkenylation reaction of olefins with alkenyl bromides has been developed, affording benzylic alkenylation products with high yields and excellent chemoselectivity. The mild conditions of the reaction preclude olefinic products from undergoing further isomerization or subsequent alkenylation. Catalytic enantioselective hydroalkenylation of styrenes was achieved by using
已开发出NiH催化的烯烃与烯基溴化物的迁移性加氢烯基化反应,可提供高收率和出色的化学选择性的苄基烯基化产物。该反应的温和条件阻止烯烃产物进行进一步的异构化或随后的烯基化。通过使用手性双恶唑啉配体实现苯乙烯的催化对映选择性加氢烯基化。
