Aqueous C-S cross-coupling: Synthesis of 2-iminobenzo-1,3-oxathioles via CuCl2·H2O-catalyzed tandem reaction of 2-iodophenols with isothiocyanates
A CuCl2·H2O-catalyzed tandem reaction of 2-iodophenol with isothiocyanate in water is described, which provides an environmentally benign, efficient, and practical route for the generation of 2-iminobenzo-1,3-oxathiole. It was notewo
