Monofluoromethyl derivatives of various nucleophiles have been synthesized using a new electrophilic monofluoromethylating reagent developed. The S-(monofluoromethyl)diarylsulfonium tetrafluoroborate has been shown to be effective for the introduction of an electrophilic monofluoromethyl group into C, S, O, N, and P nucleophiles. This methodology has been expanded for the synthesis of various biologically important compounds.

Diarylfluoromethyl sulfonium salts are efficient fluoromethylenetransfer reagents equivalent to fluorocarbene, which is difficult to access. This was demonstrated by the development of a monofluorinated Johnson–Corey–Chaykovsky reaction with ketones and aldehydes, delivering uncommon 2‐unsubstituted fluoroepoxides. This is the first evidence for the feasibility of sulfur fluoromethylylide and its

Diarylfluoromethylsulfoniumsalts, alternatives to freons or advanced fluorinated building blocks, are bench stable and easy-to-use sources of direct fluoromethylene (:CHF) transfer to alkenes. These salts enabled development of a trans-selective monofluorinated Johnson-Corey-Chaykovsky reaction with vinyl sulfones or vinyl sulfonamides to access synthetically challenging monofluorocyclopropane scaffolds

Structure‐reactivity study of a family of electrophilic monofluoromethylating reagents based on sulfonium ylide skeleton with different steric hindrance and electron‐withdrawing properties was described. These studies led us to discover two highly reactive reagents 3 with a cyclic malonate backbone and 6 with an electron‐poor 1,1,1,5,5,5‐hexafluoropentane‐2,4‐dione backbone. The high reactivity of reagent
