report a one-step procedure to selectively reduce secondary and tert-amides to their corresponding amine derivatives in the presence of an ester. This was achieved via the synergistic combination of a photoredox, a nickel catalytic system, and phenyl silane as a reductant in the presence of blue light-emitting diode light (455 nm) at room temperature. Further, this mild light-promoted dual metallaphotoredox
我们报告了一种在酯存在下选择性地将仲酰胺和叔酰胺还原为其相应的胺衍生物的一步程序。这是通过光氧化还原、镍催化系统和作为还原剂的苯基硅烷在室温下蓝色发光二极管光 (455 nm) 存在下的协同组合实现的。此外,这种温和的光促进双金属光氧化还原催化系统也成功地将内酰胺选择性还原为环胺,而不影响分子中存在的酯部分。
