Résumé/Abstract Benzo [c]-δ-aryl/alkylimino-1, 2, 5-thiadiazines (4a-g) have been obtained by the basification of henzo [c]-6-aryl/alkylimino-1, 2, 5-thiadlazine dihydroiodides (3a-g). The latter were synthesized by the oxidative cyclisation of substituted 1-aryl/alkyl-3-(2'- aminophenyl) thiocarbamides (2a-g) by ethanolic iodine. Compounds (4a-g) on acylation with acetic anhydride and glacial acetic acid in 1: 2 ratio afforded 2, 5-diacetyl derivatives ( ...
