α-Hydroxybenzylphosphonate esters are efficiently converted into α-fluorobenzylphosphonate esters by diethylaminosulphur trifluoride while the corresponding α-hydroxyallyl- and α-hydroxycinnamyl-phosphonates undergo fluorination with allylic re-arrangement; the corresponding phosphonic acids are formed by de-esterification using bromo- or iodotrimethylsilane.
α-羟基苄基膦酸酯被二乙基氨基硫三氟化物有效地转化为α-氟苄基膦酸酯,而相应的α-羟基烯丙基和α-羟基肉桂基膦酸酯则经烯丙基重排进行氟化。相应的膦酸是通过使用溴代或碘代三甲基硅烷进行酯化反应而形成的。
