of alkyl and benzyl halides using α-fluoro-α-(phenylsulfonyl)methane (1) as a highly versatile reagent is reported. Using benzyl halides, stereospecific one-pot synthesis of α-fluorovinyl compounds such as α-fluorostyrylsulfones, α-fluorocinnamates, and α-fluorochalcones has been achieved. The methodology has been extended toward the synthesis of α-substituted fluoroalkane derivatives using selective

metal-free hydrofluorination reaction of alkynyl sulfones was developed using TBAF—one of the cheapest and most commonly available fluoride sources. In addition, the reactivity of the resulting β-fluorovinyl sulfones was studied, focusing on their selective hydrogenation reaction. Both β-fluorovinyl sulfones and their hydrogenation products β-fluoroalkyl sulfones may find applications in medicinal and agrochemical
