The reaction of arylazoxy aryl sulfones with norbornene in the presence of tetrakis(triphenylphosphine)palladium(0) was found to give cis,exo-2,3-norbornane-fused 2,3-dihydrobenzo[b]thiophane 1,1,-dioxides in good yield.

Described herein is the synthesis of sulfonyl-protected azoxy compounds from nitroso arenes and iminoiodinanes by using visible light irradiation. The bench-stable sulfonyl azoxy compounds can be used in azoxy group transferreactions for C(sp3)−H functionalization of ether molecules and 1,2-difunctionalization of vinyl ethers.
