Zhao, Bin published the artcileElectrochemical fluorosulfonylation of alkenes to access vicinal fluorinated sulfones derivatives, Quality Control of 91-02-1, the publication is Tetrahedron (2022), 132651, database is CAplus.
Herein, a practical and efficient fluorosulfonylation of the various alkenes with sulfonyl radical sources and Et3N·3HF as cost-effective fluorination reagents under mild conditions is reported. Remarkably, this protocol features very green and sustainable conditions obviating the need of chem. oxidants and transition metal catalyst. A variety of substituents on both sulfonyl hydrazides and alkenes are tolerated to give vicinal fluorinated sulfones in moderate to excellent yields. Also, the synthetic utility of this transformation is further demonstrated by a gram-scale reaction and the late-stage functionalization of complex mols.
