Abstract：The reaction of 2-thiophene sulfonamide with oxalyl chloride has been investigated. The uncatalyzed reaction produced 2-thiophenesulfonyl iso cyanate and 2-thiophenesulfonyloxamide or 2-thiophenesulfonyloxamoyl chloride depending on the mole ratio of reactanta. In the presence of pyridine catalyst,however,the major product wao 2-thiophenesulfonylparabanate or mixtures of 2-thiophenesulfonyl isocyanate and 2-thiophenesulfonyl chloride. Probable mechanism of the reaction was discussed. About the optimun conditions for the synthesis of 2-thiophenesulfonyl isocyanate were determined.
