Visible light-mediated photoredox catalysis enables the chemoselective reduction of activated carbon–heteroatom bonds as a function of reduction potential. The expansion of the scope of C–X bond reductions towards less activated motifs, such as ethers, amines and sulfides, is important to both organic synthesis and macromolecular degradation method development. In the present report, exploration of
可见光介导的光氧化还原催化作用使活性炭-杂原子的化学选择性还原成为还原电位的函数。将C–X键还原的范围扩展至活化程度较低的基序,例如醚,胺和硫化物,对于有机合成和大分子降解方法的开发均至关重要。在本报告中,探索在醇类溶剂中进行光氧化还原催化可减少i Pr 2 NEt和HCO 2 H在超化学计量中减少α-酮醚,胺和硫化物的使用。另外,在不存在断裂的情况下,提供了C C键的形成,表明在这些转化中存在中间的酮基。
