An elegant cascade cross‐coupling and in situ hydrogenation reaction has been established by visible light catalysis. Combining cheap and earth‐abundant eosin Y as a photosensitizer and the cobalt chloride complex, Co(dmgH)2Cl2 (dmgH=dimethylglyoximate), as a catalyst, the desired oxidative cross‐coupling products and reductive hydrogenation products could be achieved in good to excellent yields without
通过可见光催化已经建立了一种优雅的级联交叉偶联和原位氢化反应。将廉价且富含地球的曙红Y作为光敏剂与氯化钴配合物Co(dmgH)2 Cl 2(dmgH =二甲基乙二肟酸二甲酯)作为催化剂相结合,可以很好地获得所需的氧化交叉偶联产物和还原性加氢产物在可见光照射下不使用任何外部氧化剂和还原剂的情况下达到优异的收率。
