-
In the presence of alkali nitrite and carbonate, some nitrobenzenes substituted by strongly electron withdrawing group undergo a self condensation in an aprotic polar sotvent to give symmetrical disubstituted diphenyl ethers in good yields.A possible mechanism is discussed, the nucteophilic aromatic substitution SNAr and SRMAr may occur simultaneously.
