Synthesis and characterization of some phosphazenium chloride salts, [R3PNH2]+Cl- (R = phenyl, p-chlorophenyl and morpholino)

Some phosphazenium chloride salts of the type [R3PNH 2]+Cl-, where R = phenyl, p-chlorophenyl and morpholino, were synthesized by the reaction of the corresponding phosphiniminocyclotrithiazene compounds (R3PNS

Cyclic sulphur-nitrogen compounds and phosphorus reagents: Part XIII-Reactions of cyclic sulphur-nitrogen chlorides with Ph3P-influences of tetiary base, Et3N and the ring size of the cyclothiazyl chloride on the product formation

Similar to the reactions with S4N3Cl and S3N3Cl3, triphenylphosphine reacts with five-membered cyclic sulphur-nitrogen chlorides namely, S3N2Cl and S3N2Cl2 to give triphenylphosphiniminium chloride, Ph3P=NH+2Cl- as the major product.Maximum yield (ca. 90percent) is obtained when triphenylphosphine is reacted with S3N2Cl in acetonitrile at room temperature in 2 : 1 molar ratio.Analogous reactions performed in presence of triethylamine afford two cyclothiazene products containing phosphinimino substituent.The ring size of the S - N chloride seems to determine the nature of phosphiniminocyclothiazenes formed.A rationalization of the results obtained has been attempted.
