A copper-catalyzed aerobic oxidative/decarboxylative phosphorylation of aryl acrylic acids with P(III)-nucleophiles via the Michaelis–Arbuzov rearrangement for the synthesis of β-ketophosphine oxides, β-ketophosphinates, and β-ketophosphonates is reported. The present reaction could be conducted effectively without the use of a ligand and a base. Various kinds of aryl acrylic acids and P(III)-nucleophiles
据报道,通过Michaelis-Arbuzov 重排,铜催化芳基丙烯酸与 P(III)-亲核试剂发生有氧氧化/脱羧磷酸化,合成β-酮膦氧化物、β-酮次膦酸盐和 β-酮膦酸盐。本反应可以在不使用配体和碱的情况下有效地进行。各种芳基丙烯酸和 P(III)-亲核试剂在转化过程中均可耐受,生成所需的 β-酮基有机磷化合物,作为一类有价值的含磷中间体,且收率良好至优异。此外,通过逐步控制实验和竞争实验探索了该反应可能的机理和动力学研究,结果证明该转变可能遵循二级化学动力学,并且涉及自由基过程。
