Our research group have been exploring the chemistry of sulfoxonium ylides and using these compounds in several relevant chemical transformations. Currently, we are studying the reactivity of these scaffold in the presence of diazo and hypervalent iodine. On this view, Prof. Dr. Graham Murphy at the University of Waterloo (Canada) has an extensive experience with hypervalent iodine reagents, and his group has developed several reactivity patterns and transformations such as cyclopropanation and arylation. This project aims to perform the metal free cyclopropanation and arylation reactions of sulfoxonium ylides mediated by hypervalent iodine reagent. This postdoctoral proposal will enrich the chemistry developed by our research group and contribute with the discovering new transformations involving sulfur ylides and hypervalent iodine compounds. This BEPE project has a timeline of 12 months, comprising reaction optimization studies, scope studies, and demonstration of its application in the synthesis of arylated sulfoxonium ylides and cyclopropanes.
