practical, simple, and efficient manganese‐catalysed oxidation of C(sp2)−H bond in readily available β‐carbonylenehydrazine under aerobic conditions has been developed. This protocol exhibits a wide range of functional group tolerance in β‐carbonylenehydrazines to afford α,β‐dicarbonylhydrazones. Experimental and theoretical results suggest that the reaction very likely proceeds through a radical pathway
在有氧条件下,开发了一种实用,简单而有效的锰催化氧化法,以容易获得的β-羰基肼中的C(sp 2)-H键。该方案在β-羰基肼类化合物中具有宽泛的官能团耐受性,可提供α,β-二羰基肼类化合物。实验和理论结果表明,该反应很可能是通过Mn III物种促进的氢原子转移过程通过自由基途径进行的。
