ABSTRACT:
bis(Aminophenoxy)-alpha-substituted stilbenes are prepared by reacting a dihydroxy-alpha-substituted stilbene with a halonitrobenzene in the presence of a basic acting substance such as potassium carbonate and hydrogenating the resulting bis(nitrophenoxy)-alpha-substituted stilbene to convert the nitro groups to amino groups. These compounds are useful as curing agents for epoxy resins.
