Arylseleninic acid derivative decomposition towards Se(ii)-based electrophiles: an elegant approach to construct 3-selanyl-imidazopyridines

Abstract

Benzeneseleninic acid (BSA) derivatives were used as an alternative, but extremely useful, source of Se(II)-based electrophiles, generated in situ by thermal decomposition, to construct C–Se bonds, accessing 3-selanylimidazopyridines after reaction with 2-substituted imidazopyridines. A total of thirty-four derivatives were synthesized in 50–94% yield, seventeen of which were so far unprecedented. A simple and efficient protocol is described, just delivering H2O and diaryl diselenide as by-products. Diaryl diselenides can be easily recovered during the purification process and converted again to BSA for a new reaction.
