The direct and selective conversion of a C–H bond into a C–Se bond remains a significant challenge, which is even more intricate with substrates having an innate regioselectivity under several reaction conditions, such as chalcogenophenes. We overrode their selectivity toward selanylation using palladium, copper, and the 2-(methylthio)amide directinggroup. This chelation-assisted direct selanylation
