Nitro derivatives of 1-R-1,2-benzoisothiazol-3 one 1-oxide were synthesized by the reactions of 2-alkyl(phenyl)thio-4-nitro- and 4,6-dinitro-2-(phenylthio)benzamides with chlorine in 60916 acetic acid. Analogous reactions of 2-(n-butylthio)-4-nitro- and 2-(tert-butylthio)4-nitrobenzamides with chlorine afforded 2-butyl- and 2-H-1,2-benzoisothiazol-3-one 1-oxides, respectively. The proposed reaction mechanism includes the formation and subsequent transformations of S-alkyl-S-aryl- and SS-diarylchlorosulfonium chlorides.

A new procedure was developed for the synthesis of nitriles of vic-[alkyl(aryl)sulfonyl] derivatives of benzoic, anthraquinonecarboxylic, and 4-isothiazolecarboxylic acids by the reactions of the corresponding vic-[alkyl(aryl)thio]-substituted aromatic (heteroaromatic) carboxamides with chlorine in organic solvents containing 20—65% of water. Oxidative dehydration of 1-(butylthio)anthraquinone-2-carboxamide
通过相应的 vic-[烷基(芳基)硫代]-取代芳烃的反应,开发了一种新的方法来合成苯甲酸、蒽醌羧酸和 4-异噻唑羧酸的 vic-[烷基(芳基)磺酰基]衍生物的腈类(杂芳族)甲酰胺与氯在含有 20-65% 水的有机溶剂中。1-(丁硫基)蒽醌-2-甲酰胺氧化脱水得到1-丁基-6,11-二氢-3H-1λ4-蒽[2,1-d]异噻唑-3,6,11-三酮1-氧化物副产品。后者的结构是通过 X 射线衍射分析确定的。提出了涉及形成 S-氯锍氯化物然后水解的反应方案。
