fluoride. Titration with pyridine is important for the selectivity of the reaction. Without titration the corresponding gem-difluoroethyl thioethers are generated. With titration the hydrofluorination reaction can be stopped at an intermediate stage to recover the fluorovinyl thioether, which is a relatively stable functionality to purification and manipulation. Preliminary density functional theory calculations
