as radical acceptors and SO2 sources to provide various β-ketosulfones and allylsulfones, known to be significant building blocks. Without the use of any additives including external SO2 gas, the reaction was performed under mild photoredox- or metal-catalytic conditions while tolerating various functional groups.
