Completing the cycle: Cobalt complexes I and II were found to catalyze intramolecular alkyl Heck‐type coupling reactions of alkyl iodides to alkenes upon irradiation with visible light in the presence of a tertiary amine base. The use of base is key to the catalytic turnover. The compatibility of the method with a broad range of functional groups opens opportunities for synthesis.
完成循环:发现钴配合物I和II在叔胺碱的存在下在可见光照射下催化烷基碘与烯烃的分子内烷基Heck型偶联反应。碱的使用是催化转换的关键。该方法与多种官能团的相容性为合成提供了机会。
