Abstract

We developed a practical chlorodifluoromethylation reaction mediated by diacyl peroxide generated in situ from chlorodifluoroacetic anhydride. Allylic and amino-chlorodifluoromethylations of alkenes proceeded well with the combination of this reagent, Cu(II) catalyst and a pyridine additive. Carbo- and aromatic chlorodifluoromethylations proceeded under metal-free conditions.
