direction: A modular synthesis of reagents (e.g. sodium difluoroethylsulfinate) that can be used for the direct incorporation of difluoroalkyl groups onto heterocycles is reported. The scope and generality of the incorporation of difluoroalkyl groups is exemplified with the difluoroethyl group and a proof of principle is shown for a general synthesis of fluorinated heteroarylether bioisosteres.

gem-Difluorinated organozincreagents, 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.
