Several trialkyl and two triaryl phosphites have been tested for their reactivity in the zinc iodide mediated conversion of benzyl alcohol to the corresponding phosphonates. Most react smoothly to afford the desired phosphonate diesters, including hindered and nonracemic phosphites. The implications of this reactivity on the reactions involved in the transformation are discussed.
已经测试了几种亚磷酸三烷基酯和两个亚磷酸三芳基酯在碘化锌介导的苯甲醇向相应膦酸酯的转化中的反应性。大多数反应平稳进行,以提供所需的膦酸酯二酯,包括受阻和非外消旋的亚磷酸酯。讨论了这种反应性对涉及转化的反应的影响。
