Synthesis of sulfanylated difluoroalkenes: Electrophilic difluoromethylidenation of dithioesters with difluorocarbene

Electrophilic difluoromethylidenation of dithioesters was achieved in high yields via the reaction with difluorocarbene. When aryl or alkyl dithiocarboxylates were treated with trimethylsilyl 2, 2-difluoro-2-fluorosulfonylacetate in the presence of 5 mol % of a Proton Sponge catalyst, the in situ generated difluorocarbene reacted with the dithioesters to afford 2-sulfanylated 1, 1-difluoro-1-alkenes via difluorothiiranes. This reaction can be considered as an electrophilic counterpart of the Wittig-type difluoromethylidenation of carbonyl compounds with nucleophilic difluoromethylene ylides.
