ABSTRACT:
Compounds and methods for preparing 2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidines having a formula of:wherein R1is independently selected from a group consisting of a hydrocarbyl radical, a nitro radical, and a halogen atom; “a” is an integer from 0–4; and Ar1and Ar2are each independently an aromatic radical, are disclosed. The 2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidine compounds are useful for preparing other useful monomers and polymers.
