Abstract 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 afforded 1- ...
