sources (SO2Cl2, PhICl2, Br2, and I2) gave rise to various products. In case of R = Ph, the ring-retained product, while for others, ring-degraded products were obtained. A novel cyclotrithiazene heterocycle, [Ph3PN]2S3N3+I3− containing a tetracoordinated sulfur atom with two phosphinimino substituents was obtained, which was further established by IR, NMR (1H-, 13C-, and 31P-) and elemental analysis
