Herein, a dual nickel/ruthenium strategy is developed for photoinduced decarboxylative cross-coupling between α,β-unsaturated carboxylic acids and cycloketone oxime esters. The reaction mechanism is distinct from previous photoinduced decarboxylation of α,β-unsaturated carboxylic acids. This reaction might proceed through a nickelacyclopropane intermediate. The C(sp2)–C(sp3) bond constructed by the
在此,开发了一种镍/钌双策略用于 α,β-不饱和羧酸和环酮肟酯之间的光诱导脱羧交叉偶联。反应机理不同于先前的光诱导α,β-不饱和羧酸脱羧。该反应可能通过环丙烷镍中间体进行。通过上述反应构建的 C(sp 2 )–C(sp 3 ) 键为在温和的反应条件下获得各种氰基烷基烯烃提供了一种有效的方法,它们是有机和药物化学中具有合成价值的有机骨架。该协议容忍许多关键功能组,并为复杂有机分子的修饰提供了途径。
