Chen, Yiding published the artcilePhotoredox Generation of Sulfonyl Radicals and Coupling with Electron Deficient Olefins, Quality Control of 617-52-7, the publication is Organic Letters (2020), 22(15), 5746-5748, database is CAplus and MEDLINE.
Various sulfone tetrazoles were activated via iridium photoredox catalysis in the presence of DMAP to gave dialkyl sulfones such as I [R1 = 4-FC6H4CH2CH2, 4-ClC6H4CH2, tetralin-2-yl, etc.; R2 = CN, C(O)OEt, C(O)O-Bn, etc., R3 = H, CH2C(O)OMe; R2R3 = CH2CH2OC(O); R4 = H, Me]. The presumed sulfone radical intermediates were trapped by a range of electron-deficient olefins in generally good to excellent yields.
