O,O-Dialkyl α-hydroxybenzylphosphonates (1) can be easily converted in their corresponding α-bromo (2) or α-iodo (3) phosphonates, in quantitative yield, using ,N′-carbonyldiimidazole (CDI) in the presence of allyl bromide or methyl iodide.
O,O-二烷基α-羟基苄基膦酸酯(1)可以容易地定量转化为相应的α-溴(2)或α-碘(3)膦酸酯,使用N'-羰基二咪唑(CDI)存在下。烯丙基溴或甲基碘。
