An atom‐economical and catalytic arylation of epoxide‐derived radicals is described. The key step of the catalytic system is a sequential electron and proton transfer for the rearomatization of the radical σ‐complex and catalyst regeneration. Kinetic, computational, spectroscopic, and cyclovoltammetric investigations highlight the key issues of the reaction mechanism and catalyst stabilization by collidine
描述了环氧化物衍生基团的原子经济和催化芳基化。催化体系的关键步骤是顺序进行电子和质子转移,以使自由基σ-络合物重新形成麦芽酮并重新生成催化剂。动力学,计算,光谱和循环伏安研究突出了盐酸可力丁的反应机理和催化剂稳定性的关键问题。使用杀虫剂的研究排除了阳离子作为反应性中间体的参与。
