Vicariousnucleophilic substitution of hydrogen atoms in nitroarenes with chloromethylphenyl sulfone proceeds selectively ortho to the nitro group when carried out in t-BuOK/THF base/solvent system. In the majority of 3-substituted nitrobenzene derivatives substitution occurs at the most hindered position 2. These conditions offer an efficient method of synthesis of 2,6 and 2,3-disubstituted nitrobenzene
