Dinitro- and diamino arylene disulfones

Abstract

Novel symmetrical dinitro- and diamino arylene disulfones. The dinitro compounds are prepared by the interaction of a disodium arylenedisulfinate and a p-halonitro-benzene. The diamino compounds may be prepared by reduction of the corresponding dinitro disulfones, as by means of stannous chloride, or by hydrogenation with the aid of a catalyst such as palladium or carbon.
