Carbon substituents have been introduced exclusively into the electrophilic 5-position in 1,2,6-thiadiazine 1,1-dioxides by 1,1-adduct formation with organomagnesium reagents followed by reoxidation by manganese dioxide to the conjugated, 5-substituted heterocycle.Pd(II)-catalyzed coupling reactions between organostannanes and the 4-bromo of 4-iodo derivatives have been used for the introduction of a 4-carbon substituent.Methods for chlorination, bromination or iodination in the 4-position are described.
