The action of triethylamine trihydrogen fluoride on vinyloxiranes leads, under mild conditions, to the corresponding fluorinated homoallylic alcohols. Some of these alcohols are unstable and accordingly have been converted into the corresponding more stable tosylates.

A highly regioselective rhodium-catalyzed ring-opening of vinyl epoxides with Et3N·3HF reagent to form branched allylic fluorohydrins is described. The reaction occurs at room temperature under ambient air and relies on RhCOD2BF4 as an effective catalyst, providing the desired 1,2-addition allylic fluorohydrins in moderate to good yields with excellent levels of regioselectivity.
