Coupling of gem-difluorinated organozinc reagents with S-electrophiles

[Display omitted] Copper-catalyzed or light-promoted coupling of gem-difluorinated organozinc reagents with disulfides is described. •Reactions of fluorinated organozinc reagents.•Copper-catalyzed copper-sulfur bond coupling.•Light-promoted reactions of disulfides. gem-Difluorinated organozinc reagents, which were prepared by insertion of CF2-fragment into CZn bond, couple with diethyl dixanthogen, di(benzothiazolyl) disulfide, and tetraethylthiuram disulfide. The reaction is promoted either by a copper(I) catalyst or by irradiation with blue light in the presence of Eosin Y disodium salt.
