The development of an environmentally benign sulfideoxidation procedure and its assessment by green chemistry metrics

Abstract

Different Iron (III) species were used as catalysts in sulfoxidation reactions giving excellent yields and high chemoselectivity. Among the iron (III) species, the best one was a solid β-cyclodextrin-FeBr3 complex. Sulfoxidation takes place with high chemoselectivity in the presence of other groups such as isothiocyanate. Good results were obtained when these reactions were analyzed using green chemistry metrics.
