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.
