A series of new 2-alkyl-5-arylimino-2,5-dihydroisothiazoles, substituted at position 3 with aryl and hetaryl groups and not substituted at position 4 was prepared by oxidative cyclization of N-arylamides of 3-alkylaminoprop-2-enethioic acids. The formation of the starting thioanilides was investigated by reacting the respective N-alkylimines of acetophenones with isothiocyanates. The main by-products
