| Abstract: | Fluorolactonization of unsaturated carboxylic acids under action of the electrophilic reagent F-TEDA-BF4 in ionic liquids (ILs) has been studied. This reaction proceeds in ILs faster and provides a better stereoselectivity in comparison to acetonitrile as reaction media. Gem-difluorinated γ-lactones have been synthesized by interaction of unsaturated carboxylic acids with F-TEDA-BF4 in ILs. |
