A mild, versatile and efficient method for the regioselective hydrodifluoromethylation of unactivated alkenes has been developed. This Ag-mediated Csp(3)-CF2 bond forming reaction provides easy access to a variety of vicinal alpha-difluoroacetate-containing alkanes.

We disclose a silver-catalyzed trifluoromethoxylation of N-tosyl aziridines with trifluoromethyl arylsulfonate. The protocol is characterized by its mild conditions, simple operations, and good chemo- and regioselectivity. In addition, the trifluoromethoxylation of trisubstituted aziridines could construct C-OCF3 quaternary centers exclusively, which is quite rare. This method unlocks a new catalytic
