Fluorinated Johnson Reagent for Transfer-Trifluoromethylation to Carbon Nucleophiles

A novel reagent, [(oxido)phenyl(trifluoromethyl)‐λ4‐sulfanylidene]dimethylammonium tetrafluoroborate has been developed for the electrophilic trifluoromethylation of carbon nucleophiles. The reagent was designed as a trifluorinated version of a Johnson‐type methyl‐transfer reagent. The firstexample...

Zusammenfassung:A novel reagent, [(oxido)phenyl(trifluoromethyl)‐λ4‐sulfanylidene]dimethylammonium tetrafluoroborate has been developed for the electrophilic trifluoromethylation of carbon nucleophiles. The reagent was designed as a trifluorinated version of a Johnson‐type methyl‐transfer reagent. The firstexample of vinylogous trifluoromethylation of dicyanoalkylidenes is also demonstrated.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008) A novel reagent for the electrophilic trifluoromethylation of carbon nucleophiles is described. The reagent was designed as a trifluorinated version of a Johnson‐type methyl‐transfer reagent.
