| abstract | NEW MATERIAL:A compound of formula I: (R is lower alkyl or allyl group) having a diaminodialkoxycarbonylaminoterphenyl. n EXAMPLE: 3, 3"-Diamino-4, 4"-diethoxycarbonylaminoterpheryl. n USE: A raw material for highly heat-resistant high polymers. n PROCESS: A terphenyldiamine of formula II is urethanated with ethyl chlorocarbonate in an solvent, e.g. N, N-dimethylacetamide, to form a dialkoxycarbonylamino compound of formula III, which is nitrated with the H 2 SO 4 -HNO 3 or acetic anhydride-HNO 3 system to give a dinitrodialkoxycarbonylamino compound of formula IV. The resulting compound is reduced with hydrazine or hydrazine hydrate, or ferrous sulfate to give the objective compound of formula I. n COPYRIGHT: (C)1980,JPO&Japio |
