Abstract
The present invention provides a novel one-step process for preparing substituted aryls which can be used as end-capping monomers for preparing highly branched macromolecule polymers that have highly controlled molecular architectures. The process comprises the steps of (a) reacting an aromatic acid with an activating carbodiimide for a sufficient period of time and under suitable conditions of temperature and pressure to form an activated aromatic intermediate, and (b) reacting said intermediate with a suitable nucleophile for a sufficient period of time and under suitable conditions of temperature and pressure to form said substituted aryl compound.
