and alkyl halides using either caesium carbonate in DMF or sodium dimsyl. De-esterification of 2 provided biologically important α-alkyl-α-fluoromethylenebisphosphonic acid, 3, while alkoxide–induced carbon–phosphorus bond cleavage of 2 gave α-fluorophosphonates, 4, which are useful synthons in organic synthesis.
从可商购的产品开始,已经开发出一种新的方法来生产α-烷基-α-氟亚甲基双膦酸酯2氟亚甲基双膦酸四乙酯(1),以及使用DMF中的碳酸铯或二甲基钠的烷基卤化物。的脱酯化2提供生物学上重要的α-烷基-α-fluoromethylenebisphosphonic酸,3,而醇盐诱导的碳-磷键裂解2,得到α-fluorophosphonates,4,这是有机合成中有用的合成子。
