Facile replacement of the p-fluorine atom in bis(diethylamino)pentafluorophenylphosphane [(Et2N)(2)PC6F5] by organolithium derivatives LiR (R = CH3, n-Bu, Ph), lithium alkoxides (R = OMe, OEt) and amides (NMe2, NEt2) is described. The obtained phosphanes p-R-C6F4-P(NEt2)(2) are fully characterized. Their acid-catalyzed hydrolysis affords the corresponding phosphinic acids p-R-C6F4-P(O)(H)OH, which are smoothly oxidized by treatment with a mixture of DMSO/I-2 to phosphonic acids p-R-C6F4-P(O)(OH)(2).

双（二乙氨基）五氟苯基膦作为设计新型四氟苯基膦、次膦酸和膦酸的宝贵前体

用有机锂衍生物 LiR（R = CH3、n-Bu、Ph）、醇锂（R = OMe、OEt）和酰胺轻松替换双（二乙氨基）五氟苯基膦 [(Et2N)(2)PC6F5] 中的对氟原子(NMe2, NEt2) 进行了描述。获得的磷烷 pR-C6F4-P(NEt2)(2) 得到充分表征。它们的酸催化水解得到相应的次膦酸 pR-C6F4-P(O)(H)OH，通过用 DMSO/I-2 的混合物处理将其顺利氧化为膦酸 pR-C6F4-P(O)（哦)(2).
