The dichalcogenation of imidazoheterocycles led to the first functionalization of imidazo[1,2-a]pyrimidine cores on the C6-position. The methodology, involving iodine/dimethylsulfoxide oxidation of diaryldichalcogenides, started with C3-chalcogenation, fo

Herein, we report a greener protocol for the synthesis of 3-Se/S-indoles and imidazo[1,2-a]pyridines through direct C(sp2)?H bond chalcogenation of heteroarenes with half molar equivalents of different dichalcogenides, using KIO3 as a non-toxic, easy-to-handle catalyst and a stoichiometric amount of glycerol. The reaction features are high yields, based on atom economy, easy performance on gram-scale, metal- and solvent-free conditions as well as applicability to different types of N-heteroarenes.

An efficient approach to sulfenyl imidazoheterocycles has been developed via iodine-triphenylphosphine mediated direct sulfenylation of imidazoheterocycles with sodium sulfinates. The reactions proceed smoothly under transition-metal-free conditions with a broad range of substrate scope, giving the desired products in moderate to excellent yields. This journal is
