摘要：
3-Cyanopyridine-2-sulfonyl chlorides were synthesized by the oxidative chlorination of the respective 3-cyanopyridine-2(1H)-2-thiones. It was established that 3-cyano-4,6-dimethylpyridine-2-sulfonyl chloride eliminates a SO(2) molecule at the isolation stage. N-Substituted sulfonylamides based on the latter were obtained by the reaction of the crude sulfonyl chloride with amines in an aqueous medium.
