Abstract

The efficient synthesis of a range of novel 1, 4, 2-dithiazine derivatives by ring expansion of the corresponding 1, 3-dithiolium cations in the presence of iodine and aqueous ammonia is reported; the eight π-electron 1, 4, 2-dithiazine ring is folded about the S⋯ S axis, as shown by single crystal X-ray analysis, and the heterocycle is electrochemically oxidised to yield, sequentially, the radical cation and dication species.
