Iodation of N-Aryl-2,4-dimethyl-buta-1,3-dien-1,4-sultamesBy the iodation of N-aryl-2,4-dimethyl-buta-1,3-dien-1,4-sultames 1 with I2/HgO in EtOH/AcOH the 1,2-thiazine ring is substituted. The monosubstitution occurs on the 1-position (1a, d) and the disubstitution on the 1,3-position (3a). By iodine monochloride in CHCl3 the sultames 1a-d were substituted in the (C-2)-CH3 group (4a-d), in contrast also to the results of chlorination and bromination of 1. The structure of the products 2, 3, 4 was proved by 13C-n.m.r. spectroscopic data.
