intermolecular difunctionalization strategy of styrenes with methyl thiosulfonates and arylboronic acids has been developed. This method provides an efficient and straightforward avenue to a broad range of 2,2-diarylethyl sulfone derivatives from readily available methyl thiosulfonates and commercially available styrene and arylboronic acid derivatives. The diverse substrate scope attests to the high

A visible light-induced radical cascade reaction of 2-alkynylarylethers with sodium sulfinates was established for the synthesis of sulfonyl-functionalized dihydrobenzofurans, and an intramolecular 1,5-hydrogen atom transfer was involved in this transformation. This process provided an efficient and convenient C–C formation protocol for the construction of a dihydrobenzofuran ring. Various substituents

CO2-facilitated radical sequential (3 + 2) annulation of 1,6-enynes that proceeds under the concerted catalysis of sulfinate and a photocatalyst (PC) to construct benzo-fused tricyclic scaffolds, that is tetrahydrofluorenes and their N-heterocyclic analogues, in generally good yields. This CO2-facilitated method allows the stable aromatic groups of 1,6-enynes to undergo radical addition-induced dearomatization
