Direct thiolation of aza-heteroaromatic <i>N</i>-oxides with disulfides <i>via</i> copper-catalyzed regioselective C–H bond activation

Abstract

A novel and efficient thiolation reaction of aza-heteroaromatic <italic>N</italic>-oxides with disulfides <italic>via</italic> copper catalyzed C–H activation has been developed.
