dimethylamino-fluorophosphonitriles NnPnF2n–x(NMe2)x(x= 1–3, n= 3–6) have been prepared by the reaction of the phosphonitrilicfluorides (NPF2)n with (a) dimethylaminotrimethylsilane at 100°(b) dimethylamine in diethyl ether at 0°. Except for n= 6, reaction (a) gives the higher yields of mono-substituted derivatives (x= 1). The 1H and 19F n.m.r. spectra show that successive dimethylamination takes place non-geminally
二甲基氨基氟代腈N n P n F 2 n – x(NMe 2)x(x = 1-3,n = 3–6)是通过使磷腈氟化物(NPF 2)n与(a)反应制得的。二甲基氨基三甲基硅烷在100°(b)二甲胺的乙醚溶液中,在0°。除n = 6外,反应(a)产生更高产率的单取代衍生物(x = 1)。的1 H和19F nmr光谱表明,连续的二甲基胺化是非双键发生的。二甲基氨基氟膦腈与无水氯化氢或溴化氢在25°(n = 4-6)或100°(n = 3)下反应,生成相应的氯化物和溴化物。讨论了二甲基氨基氟膦腈的ir和31 P nmr光谱以及单卤代氟膦腈的19 F nmr光谱,并描述了磷腈氟化物的单异硫氰酸根合衍生物的制备。
