3-Oxoisothiazolopyridines were synthesized for the first time by the reaction of 3-cyanopyridine-2-thiones or bis(3-cyanopyridyl) disulfides with concentrated sulfuric acid.It is demonstrated that 3-carbamoylpyridine-2-thiones are formed as intermediates.The 3-oxoisothiazolopyridines were converted to 3-bromoisothiazolopyridines and pyridine-2-thiones.The bromination of pyridine-2-thione was studied.
