Bis quinoline peri acids

Preparation of a novel heterocyclic peri acid is initiated by reacting diaminodimethylbiphenyl with methyl vinyl ketone to produce tetramethyl biquinoline. The substituent methyl groups are oxidized subsequently to produce a tetraacid, or upon dehydration of the tetraacid, a dianhydride. The peri ac...

Zusammenfassung:Preparation of a novel heterocyclic peri acid is initiated by reacting diaminodimethylbiphenyl with methyl vinyl ketone to produce tetramethyl biquinoline. The substituent methyl groups are oxidized subsequently to produce a tetraacid, or upon dehydration of the tetraacid, a dianhydride. The peri acids of this invention have the following structural formula: WHERE R may be either O PARALLEL --C ANGLE O --C PARALLEL O or (-COOH)2 and R' is -H, -OCH3,
