Reactions of difluorocarbene with benzyl and alkylzinc halides leading to fluorinated organozinc species have been described. The generated α-difluorinated organozinc reagents are reasonably stable in solution and can be quenched with external electrophiles (iodine, bromine, proton), affording compounds containing the CF2 fragment.

A method for the synthesis of β,β‐difluorinated ketones by coupling of α,α‐difluorinated iodides with silyl enol ethers is described. The reaction is performed in the presence of iridium(III) photocatalysts under the irradiation with 400 nm light emitting diodes.
