Nitrosation of 2-Aryl-3,5-dimethyl-1,1-dioxo-1,2-thiazines - an Unusual Ringtransformation to Mesoionic Pyridazinium Salts

The thiazines 1b-e, g, h react with isoamyl nitrite/HClg by nitrosation of the 3-methyl group to the 3-cyano-thiazines 3b-e, g, h.As by-products the mesoionic pyridazinium salts 4b, c are formed.The compounds 4b-i and 4-1e-i became main products by nitros

Structure Elucidation of Bromination Products of N-Aryl-2,4-dimethyl-buta-1,3-diene-sultames-1,4

The structure of bromination products of N-aryl-2,4-dimethyl-buta-1,3-diene-sultames-1,4 1a-d, f is determined by 13-C-n.m.r. spectroscopy.As mono bromination product of N-phenylsultam 1a the 4-bromomethyl derivative 2a was isolated.Dibromination of sultames 1 yields 1-brom-4-brommethyl-sultames 3 and by tribromination 1,3-dibrom-4-brommethyl-sultames 4 are obtained.
