FLUORIDOLYSIS OF N-PHOSPHORYL PHOSPHAZENE S

In the reaction of the N-phosphoryl phosphazenes X(3)P=N-P(Y)X(2) (X=C l, PhO, Et(2)N, CF3CH2O, PrS, Ph; Y=O, S) (1-18) with Et(3)N . nHF (n approximate to 3 or 0.6) fluoro derivatives of N-phosphoryl phosphazen es (see table 2) as well as N-phosphorylated imidotetrafluorophosphate s, [F4P=N-P(Y)Cl-2](-) (Y=O, S), and imidopentafluorophosphates, [F5P- N-P(Y)X(2)](2-) or [F5P-NH-P(O)X(2)](-) (see table 3), are formed. t-B uNHPCl(2)=N-POCl2 reacts in acetonitrile with Et(3)N or i-Pr(2)EtN to form a product, representing probably the diazadiphosphetine [t-BuN-PC l2=N-P(O-)Cl-2](-) (5 b).
