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

Fanghaenel, E.,Mohamed, H.,Keita, Y.,Radeglia, R.

, p. 353 - 361 (2007/10/02)

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.
