Abstract

Compounds and methods for preparing 2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidines having a formula of: wherein R 1 is 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 Ar 1 and Ar 2 are 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.

Claims (10)

1. A para, para-2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidine having a formula:

wherein R 1 is 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 Ar 1 and Ar 2 are each independently an aromatic radical.

2. The para, para-2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidine of claim 1 , wherein Ar 1 and Ar 2 are each independently a monocyclic aromatic radical.

3. The para, para-2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidine of claim 2 , wherein Ar 1 and Ar 2 are phenylene radicals.

4. The para, para-2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidine of claim 2 , wherein “a” is 0.

5. The para, para-2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidine of claim 1 , having a formula:

wherein R 1 is independently selected from a group consisting of a hydrocarbyl radical, a nitro radical, and a halogen atom; “a” is an integer from 0–4.

6. The para, para-2-aryl-3-aminoaryl)-3-(hydroxyaryl)phthalimidine of claim 5 , wherein “a” is 0.

7. A 2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidine having a formula:

wherein R 1 is independently selected from a group consisting of a hydrocarbyl radical, a nitro radical, and a halogen atom; “a” is an integer from 0–4.
