Carbanions of diethyl benzylphosphonate and diethyl 1-phenylethylphosphonate add to nitroarenes to form relatively long-lived σH adducts that can be oxidized to products of oxidative nucleophilic substitution of hydrogen. By variation of the conditions, o- and p-nitroarylated derivatives of the starting phosphonates can be synthesized regioselectively. It has been proven that addition of carbanions
