Abstract
PURPOSE: To obtain the title compounds useful as raw materials for medicines, pesticides, etc. without using polar aprotic solvents, by reacting halonitrobenzenes with carbonates or hydrogencarbonates of alkali metals in the presence of nitrous ions and diamines easily.
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. potassium carbonate, etc., or hydrogencarbonates in the presence of nitrous ions, e.g. sodium nitrite, etc., in an amount of 0.005W0.5n mole per mole of the starting compounds, and diamines, e.g. triethylenediamine, etc., in an amount of 0.005W0.5 mole per mole of the starting compounds to give dinitrobiphenyl ethers, e.g. bis(4-nitrophenyl)ether, etc., of formula II
