Abstract
Chlorodifluoromethyl group was introduced into aromatic rings using bis(chlorodifluoroacetyl) peroxide which was readily prepared from corresponding acid anhydride with 30% hydrogen peroxide, and the chlorine was successively replaced by hydrogen or allyl group in excellent yields under radical conditions.Keywords
