Abstract
Abstract The animation of bromanil with 2,5-diaminobenzenesulphonic acid at 60°C, unlike that of chloranil, leads to the total loss of halogen. Reaction at 0°C, however, results in the formation of 2,5-bis-(4-amino-3-sulphoanilino)-3,6-dibromo-1,4-benzoquinone. This dianilide, unlike the corresponding dichloro derivative, is readily reduced by warming it in aqueous solution with an excess of 2,5-diaminobenzenesulphonic acid.
