STUDIES IN THE HETEROCYCLIC COMPOUNDS: I. SOME 2-THIOPHENESULFONYL DERIVATIVES

Abstract

2-Thiophenesulfonyl chloride, prepared by treating thiophene with chlorosulfonic acid, has been condensed with nucleophilic reagents: ammonia, cyclohexylamine, N-methylaniline and sodium azide to afford the sulfonamide. N-cyclohexyl sulfonamide. N.N-methylphenyl sulfonamide and the sulfonyl azide respectively. The sulfonyl azide has been reacted with triphenylphosphine, tri-n-butylphosphine, norbonene and cyclohexene. The ir and nmr spectral characteristics of the products are very briefly discussed.
