A new bench stable reagent that is easily synthesized and handled is investigated for its use in radical prenylation of diverse organic molecules. It has demonstrated high functional group compatibility and can be used with numerous photocatalytic methods to give prenylated products from aryl iodides, bromides, anilines, thiols and alkyl halides.

synthesis of sulfone compounds with diverse structures by visible-light-catalyzed radical–radical cross-coupling of sulfonylchlorides and trifluoroborate salts. Allyl, benzyl, vinyl, and aryl trifluoroborates can be successfully cross-coupled with (hetero)aryl and alkyl sulfonylchlorides, respectively. This strategy features redox neutrality, good substrate generality, simple operation, and benign reaction

Allyl sulfones are commonly present in bioactive compounds and organic building blocks. This work introduces a photocatalytic radical addition–elimination reaction involving readily accessible sulfonyl chlorides and allyl bromides. It delivers structurally diverse allylic sulfones in moderate to excellent yields, showcasing a high tolerance to functional groups. Notably, this method operates under
