Selective O-benzoylation of hydroxamic acids is achieved by the treatment of BPO and DABCO. Aliphaticalcohols are not reactive under these conditions. Various radical or oxidation sensitive functional groups are compatible with this protocol, and no anhydrous reagents or solvents are required for the high yields of the benzoylations.
