Herein we report a photocatalytic oxidative radical addition reaction for the synthesis of unsymmetrical 1,4-dicarbonyl compounds. This reaction utilizes a desulfurization process to generate electrophilic radicals, which add to α-halogenated alkenes and undergo further oxidation to deliver 1,4-dicarbonyl compounds. This mild and highly efficient method provides a valuable alternative to known strategies.

The Diels-Alder cycloaddition of o-chloranil with phenylacetylenes substituted with chlorine in the ring can afford chlorobiphenyls upon photodecomposition of the brodged diketone adduct.Biphenyls derived from 3-chloro-, 4-chloro-, 2,4-dichloro-, and (2,5
