AMINOLYSIS OF P-TRICHLORO-N-DICHLOROPHOSPHORYLMONOPHOSPHAZENE AND THECRYSTAL-STRUCTURE OF NYL)-2-CHLORO-2,2-BIS(DIISOPROPYLAMINO)PHOSPHAZINE

The reactions of Cl3P=N-P(O)Cl-2 (1) with primary and secondary amines have been studied. The following monophosphazenes, (RRN)(3)P=N-P(O)(N RR)(2), and bis(phosphinoyl)amines, [(RRN)(2)P(O)]2NH were isolated: N RR = NHCH(2)Ph, NEt(2), NH(CH2)(2)CH3 groups for monophosphazenes, and NEt(2), NH(CH2)(2)CH3 for phosphinoyl amines. The unexpected geminal phosphazene, Cl(RRN)(2)P=N-P(O)Cl-2, {RRN = N[CH(CH3)(2)](2)}, was als o obtained in moderate yield. The spectral data (IR, H-1, C-13, and P- 31 NMR, and MS) are presented. The structure of lorophosphinyl)-2-chlo ro-2,2-bis(diisopropylamino) phosphazene (5) was determined by X-ray c rystallography. The basicities of these and related compounds in nonaq ueous nitrobenzene solution were obtained by potentiometric titration.
