Miao, Wenjun published the artcileIron-Catalyzed Difluoromethylation of Arylzincs with Difluoromethyl 2-Pyridyl Sulfone, Product Details of C11H8F2, the publication is Journal of the American Chemical Society (2018), 140(3), 880-883, database is CAplus and MEDLINE.
In the presence of Fe(acac)3 and N,N,N’,N’-tetramethylethylenediamine, arylzinc reagents (in most cases generated in situ from aryl Grignard reagents) underwent difluoromethylation reactions with difluoromethyl 2-pyridinyl sulfone at -40° to ambient temperature to yield difluoromethylarenes. Reaction of a difluoropentenyl 2-pyridinyl sulfone with an in situ-generated diarylzinc reagent yielded an arylmethyldifluorocyclopentane, implying the involvement of radical species in the iron-catalyzed difluoromethylation; the reaction was inhibited by TEMPO, BHT, and 1,4-dinitrobenzene.
