In conclusion, we have disclosed a novel arylsulfonylacetate skeleton in which aryl rings are tethered to acetates through SO2, as a powerful bifunctional reagent for the alkylarylation of alkynes under photoredox conditions. This modular bifunctional reagent allows for the simultaneous incorporation of (hetero)aryl ring and alkyl carboxylate into alkynes, facilitating the synthesis of a diverse library of synthetic valuable all-carbon tetrasubstituted alkene derivatives. This method features mild reaction conditions, high atom-and step-economy, excellent functional group compatibility and great structural diversity. Given the current easy availability of arylsulfonylacetate bifunctional reagents, along with the ubiquity of alkynes as feedstock substrates, we anticipate this method would serve as a highly enabling platform for research endeavors aimed at synthesizing synthetic useful all-carbon tetrasubstituted alkenes in a single operation. Further investigations are currently underway in our laboratory to address the application of these bifunctional reagents in a stereo controlled manner.
