N-Heterocyclic Iod(az)olium Salts - Potent Halogen Bond Donors in Organocatalysis

Boris Nachtsheim University of Bremen

Abstract

Herein we describe the first systematic investigation of cyclic iodonium salts (iodoliums and iodazoliums) and their performance as XB-donors in a variety of benchmark reactions. It was found that further N-alklyation of the N-heterocycle has a significant influence on their XB-donor capability. These novel dicationic species show a reactivity which is comparable or even better than the best so far described iodine(I) and iodine(III) compounds throughout the investigated reaction set.
