A series of phosphine oxides and H-phosphinates were vinylated in the presence of the iodine(iii) reagents vinylbenziodoxolones (VBX), providing the corresponding alk-1-enyl phosphine oxides and alk-1-enyl phosphinates in good yields with complete chemo- and regioselectivity. The vinylation proceeds in open flask under mild and transition metal-free conditions.
在碘（III）试剂乙烯基苯并碘氧杂环戊二酮（VBX）存在下，一系列氧化膦和次膦酸氢酯发生乙烯基化反应，以良好的产率、完全的化学选择性和区域选择性得到相应的1-烯基氧化膦和1-烯基次膦酸酯。乙烯基化反应在敞口烧瓶中、温和且无过渡金属的条件下进行。
