Relay cooperation of K2S2O8 and O2 in oxytrifluoromethylation of alkenes using CF3SO2Na†
Abstract
A new radical oxytrifluoromethylation of alkenes via an aerobic Cvinyl–heteroatom bond oxygenation process is reported, in which O2 and a catalytic amount of K2S2O8 work in concert to activate CF3SO2Na. Mechanistic investigation disclosed that CF3SO2˙ could react with O2 to reinitiate radical chain process.
