 Abstract: During investigations on our deaminative chlorination protocol, a misassignment between two constitutional isomers of a benzofused isothiazole was encountered. Herein, we provide a clue game in order to identify the correct structure of the reported molecule as well as an investigation on the origin of the error. Finally, a revised synthesis of the previously published examples was proposed to provide the practitioners reliable data en route to reproducible science.
