1H- and 13C-N.M.R. Spectroscopic Investigations of Substituted 1,1-Dioxo-1,2-thiazines; Additivity of the Substituent Effects

The influence of various XCH2 substituents (X: Cl, Br, I, SCN, SO2CH3, SC(NH2)2+, Py+) in the 3-, 5- and 3,5-position of the 1,1-dioxo-2-phenyl-1,2-thiazine on the 1H- and 13C-n.m.r. chemical shifts of the ring atoms is described.The substituent effects are additive.The 1H- and 13C-n.m.r. chemical shifts of the 3,5-disubstituted 1,1-dioxo-1,2-dithiazines can be calculated from increments derived from the 3- and 5-substituted compounds.

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.
