ABSTRACT:
An aminoarylaminoarazole can be prepared by a process comprising the steps of condensing a condensable nitroarylcarbonyl compound with an aminonitroarylol, an aminonitroarylthiol, or a triaminonitroarene to form a dinitroanilide, then reducing and cyclizing the dinitroanilide under such conditions to form the aminoarylaminoarazole. The aminoarylaminoarazole is useful in making PIBX polymers.
