Benzenehexabromide was found to afford photochemical bromination of substituted acetanilide in the p-position.The rates of bromination were found to follow the order predicted on the basis of inductive effect of the substituents and similar to the sequence of reactivities observed for bromination of acetanilides with N-bromosuccinimide.Similar results were obtained in the case of p-substituted benzanilides and the reaction shows a good Hammett correlation with the ?+ values for the substituents with a ρ value -0.266.

Bromomethyl-1,2,5-thiadiazoles 2a-c were prepared by bromination of methyl-1,2,5-thiadiazoles 1a-c by NBS in refluxing carbon tetrachloride.When bromination of 1a and 1b was carried out under irradiation of tungsten lamp, mixtures of cis-5a and b and tran
