Abstract
Reactions of sodium N-chlorobenzenesulfonamides (1a–1e) with N-alkylthioxo-dihyderivates of the following heterocycles (A) have been studied: quinoline, isoquinoline, thiazole, isothiazole, benzothiazole, 1,2-benzisothiazole, 2,1-benzisothiazole, 1,2-benzisothiazole 1,1-dioxide. Reaction products are N-arylsulfonyl-S-(dihydroheteroarylidene)sulfimides (B), N,N'-bis(arylsulfonyl)heteroareniumsulfinamidinates (C) and N-(dihydroheteroarylidene)arensulfonamides (D). Oxidation of some sulfimides (B) gives N-(arylsulfonyl)heteroareniumsulfonamidates (E). The situation of bonding is discussed for B–E.

Die Oxidation einiger Sulfimide (B) führt zu N-(Arylsulfonyl)heteroareniumsulfonamidaten (E). Für B–E werden die Bindungsverhältnisse diskutiert.
