Abstract

PURPOSE: To obtain the title compounds useful as raw materials for medicines, pesticides, synthetic resins, etc., by reacting halonitrobenzenes only with alkali metal carbonates or hydrogencarbonates in the presence of nitrous ions in a polar aprotic solvent.
CONSTITUTION: Halonitrobenzenes, e.g. p-chloronitrobenzene, etc. of formula I: (X is halogen; Y1 and Y2 are H, alkyl, alkoxy, or carboxyl groups; n is 1 or 2, at least one of the nitro groups is at the o- or p-position to X) are reacted with alkali metal carbonates, e.g. sodium carbonate, etc., or hydrogencarbonates in the presence of nitrous ions, e.g. sodium nitrite, etc., in an amount of 0.005W0.5 mole per mole of the starting materials in a polar aprotic solvent, e.g. dimethyl sulfoxide, etc. to give dinitrobiphenyl ethers, e.g. bis(4-nitrophenyl)ether, etc. of formula II.
EFFECT: Expensive K salts are unnecessary
