Cyclische Sulfoximide, VI. 3‐Imino‐3 H ‐1λ 4 ,2‐benzisothiazol‐1‐oxide

2-Sulfinylbenzamide 3 reagieren mit Stickstoffwasserstoffsaure zu 3-Imino-3H-1λ4,2-benzisothiazol-1-oxiden 4, die durch Substitution am Imin-Stickstoff die Derivate 9–12 liefern. Cyclic Sulfoximides, IV. 3-Imino-3H-1λ4,2-benzisothiazole 1-Oxides 2-Sulfinylbenzamides 3 react with hydrazoic acid to yield 3-imino-3H-1λ4,2-benzisothiazole 1-oxides 4. The derivatives 9–12 are obtained by substitution at the imino-nitrogen.
