What the study found
The study reports a pentafluoroethyl sulfoximine reagent that can be used to pentafluoroethylate styrene derivatives under mild photocatalytic conditions. It also enables difunctionalization with simple nucleophiles, adding the pentafluoroethyl group together with C-O, C-N, C-S, or C-C bond formation.
Why the authors say this matters
The authors conclude that this approach significantly broadens the scope of pentafluoroethylation difunctionalization compared with previous copper-based methods.
What the researchers tested
The researchers synthesized a pentafluoroethyl sulfoximine and tested it as a source of pentafluoroethyl radical in photocatalytic reactions with styrenes. They used simple nucleophiles to examine whether the reaction could introduce the pentafluoroethyl group and form different bond types in the same transformation.
What worked and what didn't
The reagent worked as a pentafluoroethyl radical source under mild photocatalytic conditions. The abstract states that pentafluoroethylation-difunctionalization was achieved with simple nucleophiles and that C-O, C-N, C-S, and C-C bonds could be formed. The abstract does not describe unsuccessful cases or detailed reaction limits.
What to keep in mind
The abstract does not provide detailed substrate scope, yields, selectivity data, or specific limitations. It also does not describe which styrene derivatives or nucleophiles performed best or worst.
