Preparation of 2,2′-dinitrobiphenyl

Preparation of 2,2'-dinitrobiphenyl

Preparation of 2,2′-dinitrobiphenyl

A cold solution of 21.6 g of copper(I) chloride in 100 ml of conc, hydrochloric acid is added to the diazonium solution prepared from 30 g of o-nitroaniline, 45 g of conc, sulphuric acid, 60 ml of water and 15.3 g of sodium nitrite. During the addition of the copper salt the whole is vigorously stirred. There is a brisk evolution of nitrogen, the mass turns black and a brownish-yellow substance is precipitated. When the liquid becomes green, the reaction is finished. The product is distilled in steam until no more o-chloronitrobenzene passes over. There remains in the distilling flask almost pure 2,2′-dinitrobiphenyl. It is filtered off, dried, and recrystal­lised from benzene. The yield of 2,2′-dinitrobiphenyl is 30%; 2,2′-Dinitrobiphenyl is a crystalline solid; m.p. 127° C;
