Abstract
Method of preparing aromatic bisimides by effecting a reaction between a 3-substituted N-arylphthalimide and an aromatic dihydroxy dianion compound by refluxing in a non-polar organic solvent. Advantageously, the method eliminates the need for using a phase transfer catalyst or a dipolar aprotic solvent.
