A photoredox strategy to access β-selenated cyclic ketone derivatives through the
coupling reaction of 1-(1-arylvinyl)cyclobutanols with diselenides under blue LED
irradiation and an air atmosphere was developed. This reaction employs the easily
accessible and shelf-stable diselenides as a selenium radical source, and the reaction
has advantages of mild reaction conditions and broad substrate scope.
