efficient visible light photocatalytic strategy to synthesize thermodynamically less stable Z-arylvinyl halides (with up to >99/1 Z/E ratio and 86% yield) was developed. The reaction combined base-mediated halodecarboxylation of E-arylvinyl acids with N-halosuccinimide and visible light Ir-photocatalyzed isomerization of E-arylvinyl halides in a one pot sequential catalytic process.
开发了一种有效的可见光光催化策略来合成热力学上不太稳定的Z-芳基乙烯基卤化物( Z / E比高达 >99/1 ,产率为 86%)。该反应将碱介导的E-芳基乙烯基酸与N-卤代琥珀酰亚胺的卤化脱羧反应和可见光 Ir 光催化的E-芳基乙烯基卤化物的异构化在一锅顺序催化过程中结合起来。
