Abstract : In this chemical puzzle fluoromethyldimethylamine represents a versatile reactant for the synthesis of electron‐deficient, functionalized phosphates. Thus, the oxidative addition of the reagent to (C2 F5 ) n PF3− n ( n =1–3) selectively affords zwitterionic [(C2 F5 ) n F5− n P(CH2 NMe2 CH2 NMe2 )] ( n =1–3) in good yields. The course of the reaction involved the phosphoranide [P(C2 F5 )3 F] −, which was evidenced independently. Treatment of [(C2 F5 )3 F2 P(CH2 NMe2 CH2 NMe2 )] with aqueous sodium hydroxide gave rise to the formation of the phosphate Na + [(C2 F5 )3 F2 P(CH2 NMe2 )] − . The nucleophilic nitrogen atom in the phosphates [(C2 F5 ) n F5− n P(CH2 NMe2 )] − allows the synthesis of several novel functionalized perfluoroalkylfluorophosphates. See the Full Paper by B. Hoge et al. for more details.
