The title compounds were refluxed in hexanol to give quantitatively the O-hexyl aryl-4-pentenylphosphinate derivatives via transient monomeric metaphosphinates, which seem to be formed by the phospha-Cope rearrangement. Kinetic studies show that the reaction rate increases with an increase in the magnitude of the positive charge on the phosphorus atom.
标题化合物在己醇中回流,通过瞬时单体偏膦酸盐定量生成 O-己基芳基-4-戊烯基膦酸盐衍生物,这些衍生物似乎是通过磷-科普重排形成的。动力学研究表明,随着磷原子上正电荷量的增加,反应速率也随之增加。
