coupling of aryl bromides and cyclic secondary alkyl bromides catalyzed by nickel/spiro-bidentate-pyox ligands with lithium chloride as the additive for the Csp2–Csp3 bond formation was reported. The reaction could tolerate functional groups such as sulfonamide, ester, aldehyde, ketone, protected indolyl, tert-butoxycarbonyl, aryl nitriles and aryl chloride. Various aryl-cyclic secondary alkyl Csp2–Csp3 bond
报道了由镍/螺-双齿-pyox 配体催化的芳基溴化物和环状仲烷基溴化物与氯化锂作为 Csp 2 -Csp 3键形成添加剂的交叉亲电偶联。该反应可以耐受磺酰胺、酯、醛、酮、受保护的吲哚基、叔丁氧羰基、芳腈和芳基氯等官能团。在最佳反应条件下合成了各种芳环仲烷基 Csp 2 -Csp 3键产物(19 个实例)。
