A generally applicable and robust regio- and stereoselective cross-dehydrogenative-coupling of enamides with ethers or alkanes via transition-metal-free photoredox-catalysis under environmentally benign and atom economic conditions is demonstrated. The visible-light-induced transformations proceed smoothly with the aid of non-expensive and non-poisonous organic dyes, forging geometrically defined and synthetically paramount β-alkylated enamides with broad substituent diversity and functional group compatibility.

通过光氧化还原催化的交叉脱氢偶联反应烯酰胺与醚或烷烃的无过渡金属区域选择性和立体选择性 C(sp2)–C(sp3) 偶联

证明了在环境友好和原子经济条件下通过无过渡金属光氧化还原催化烯酰胺与醚或烷烃的普遍适用且稳健的区域和立体选择性交叉脱氢偶联。可见光诱导的转变在非昂贵和无毒的有机染料的帮助下顺利进行，形成了具有广泛取代基多样性和官能团相容性的几何定义和合成最重要的 β-烷基化烯酰胺。
