Ni-catalyzed decarboxylative C(sp3)−N cross-coupling of redox active ester and oxime esters was realized through electrochemical cathodic reduction. Mechanistic studies unveil a high-valent nickel species-driven reductive elimination pathway, rather than direct radical-radical coupling. The utility of this methodology was demonstrated through a broad scope (1°, 2°, 3° carboxylic acids) and late-stage
通过电化学阴极还原实现了氧化还原活性酯和肟酯的镍催化脱羧C(sp 3 )−N交叉偶联。机理研究揭示了高价镍物质驱动的还原消除途径,而不是直接的自由基-自由基耦合。该方法的实用性通过复杂分子的广泛范围(1°、2°、3°羧酸)和后期功能化得到了证明。
