Abstract

CuII-promoted aerial oxidation of a series of benzothiadiazines (1) under ambient conditions affords the first structurally characterised examples of thiadiazine S-oxides (2). The isolation of the homoleptic CuII 3-(2′-pyridyl)benzothiadiazide-S-oxide complex provides insight into the reaction mechanism.
