Abstract
The well-defined Pd(I) metalloradical [Pd(PBu)] reacts with aryl and alkyl iodides at room temperature, yielding [Pd(PBu)(μ-I)] and phosphonium salts. Pd(II) aryl/alkyl derivates, reflecting net radical oxidative addition of the substrate to the metalloradical, are generated during the reaction and two examples have been isolated and crystallographically characterised.
摘要
结构明确的 Pd(I) 金属自由基[Pd(PBu)]在室温下与芳基和烷基碘化物反应，生成[Pd(PBu)(μ-I)]和鏻盐。在反应过程中生成了 Pd(II) 芳基/烷基衍生物，反映了底物向金属自由基的净自由基氧化加成，其中两个例子已被分离并通过晶体学进行了表征。
