A range of nitro compounds are smoothly reduced to their corresponding oximes under the synergistic effects of visible light irradiation, the Ru(bpy)3Cl2 photocatalyst, Hünig’s base, Mg(ClO4)2 activation, and MeCN solvent. This remarkably mild and environmentally benign protocol, when orchestrated with classical Beckmann rearrangement, enables such high-value industrial feedstock as caprolactam to
在可见光辐射,Ru(bpy)3 Cl 2光催化剂,Hünig碱,Mg(ClO 4)2活化和MeCN溶剂的协同作用下,一系列硝基化合物被平滑还原为相应的肟。当采用经典贝克曼重排进行编排时,这种非常温和且对环境无害的方案使得从简单的前体硝基环己烷中即可轻松获得诸如己内酰胺之类的高价值工业原料。
