The reaction of a trialkyl phosphite with trimethylsilyl iodide, which leads to O-trimethylsilyl esters of alkylphosphonic acid, has been shown to involve several steps, all of which are defined. The first step is the formation of the iodophosphite, involving a four centre mechanism in which PIII plays the role of electrophile. This is in contrast to the analogous reaction of phosphates with alkyl
已显示亚磷酸三烷基酯与碘化三甲基甲硅烷基酯的反应导致烷基膦酸的O-三甲基甲硅烷基酯的反应涉及多个步骤,所有步骤均已定义。第一步是形成碘代亚磷酸酯,涉及四个中心机理,其中P III发挥亲电试剂的作用。这与磷酸盐与烷基卤化物的类似反应(Arbuzov反应)相反,后者从磷的亲核进攻开始。
