By substitution of a halogen atom in cyclic phosphazenes by isocyanate or isothiocyanate new members of this class of compounds are synthesized. These compounds are fairly stable against hydrolysis. Reaction of the new compounds with amines yields
P3N3F5NHC(O)N(CH3)2 and P3N3F5NHC(S)N(CH3)2. With elemental chlorine P3N3F5N = CCl2 is formed. Numerous IR, NMR and mass spectra data of the new compounds are reported.
P3N3F5NHNH2 reacts with P3N3F5Br to yield the symmetric hydrazide P3N3F5-NHNHP3N3F5. Compounds of the type P3N3F5NHNHC(O)CX3 and P3N3F5NHN = CX2 are readily prepared from P3N3F5NHNH2 and carbonic acid chlorides and respectively aldehydes and ketones.
The reaction product of P3N3F5NHNH2 and CH3CH2CHO gives a dimeric derivate. Its structure was proofed by molecular weight, IR- and mass spectra.
