The first palladium-catalyzed direct monofluoromethylation of arylboronic esters to produce monofluoromethyl arenes is reported. The reaction is typically carried out at room temperature within 4 h and has a good functional group tolerance. The monofluoromethylating agent, CH2FI, was readily prepared via a halogen-exchange process.

An operationally simple and selective method for the direct conversion of benzylic C-H to C-F to obtain mono- and difluoromethylated arenes using Selectfluor as a fluorine source is developed. Persulfate can be used to selectively activate benzylic hydrogen atoms toward C-F bond formation without the aid of transition metal catalysts.

The selective fluorination of compounds containing benzylic hydrogen atoms was accomplished by electrolysis in a mixture of 70% HF and 30% pyridine (Olah's reagent) using a square wave alternating current (1.76-2.75 V, 0.02-0.05 Hz) and Pt electrodes. This method can be used in the laboratory to prepare conveniently gram-size quantities of monofluorinated products. An ion radical mechanism has been proposed.
Influence of an α-Cyano Function on Charge Delocalization in the Benzyl Cation. Relationship between Inductive Destabilization and Conjugative Stabilization by the Cyano Group
Gassman, Paul G.,Guggenheim, Thomas L.
, p. 3023 - 3026 (2007/10/02)
The solvolytic behavior of a series of substituted acetophenone cyanohydrin methanesulfonates has been studied in 2,2,2-trifluoroethanol.A ρ value of -6.70 was observed when the rate data was evaluated vs.Brown's ?+ values.
