Preparation and catalytic properties of benziodolium salts

Abstract

Dibenziodolium salts have recently emerged as useful iodine(III)-type halogen bonding (XB) donors. However, although benziodolium salts with one less benzene ring are expected to exhibit different reactivity from dibenziodolium salts, their function as an XB donor has not been clarified. Herein, a new and simple synthetic method of benziodolium salts and their application as organic Lewis acids are reported.
