A novel cyclic sulfilimine, 2-methyl-2,4,1 -benzodithiazin-2-ium-1 -ide (4) was synthesized by deprotonation of the corresponding azasulfonium salt (3) with base. The compound 4 was oxidized with potassium permanganate to afford the sulfoximine 5, exclusively. On refluxing in several solvents, compo
