Abstract
PURPOSE: To obtain title compound for medicines, etc. in high yields, by adding water to the reaction system in reacting a halonitrobenzene with a hydroxide, carbonate, or hydrogencarbonate of an alkali metal in the presence of nitrous ions in a polar solvent to increase the reaction rate.
CONSTITUTION: A halonitrobenzene, 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; one of the nitro group is at the o-or p-position to X) is reacted with a hydroxide, carbonate, or hydrogencarbonate of an alkali metal, e.g. sodium carbonate, etc. in the presence of nitrous ions, e.g. sodium nitrite, etc. in a polar solvent, e.g. dimethyl sulfoxide, etc. to give a dinitrobiphenyl ether, e.g. bis (4-nitrophenyl) ether, etc., of formula II.
EFFECT: An alkali metal hydroxide can be used as an alkali source.
