Abstract:
1. A process of preparing an aromatic carboxylic acid having a heteroatom containing substituent ortho, meta, or β of said carboxylic acid comprising: reacting in a reaction vessel an aromatic precursor having an aromatic core having at least one heteroatom containing substituent and at least one hydrogen with a haloacetonitrile under reaction conditions to form an aromatic acetonitrile with an acetonitrile moiety and at least one heteroatom containing substituent, said heteroatom containing substituent ortho, meta, or β of said acetonitrile moiety; exposing said aromatic acetonitrile having at least one heteroatom containing substituent to an oxidizing agent under conditions to convert the acetonitrile moiety into a carboxylic acid group to prepare said aromatic carboxylic acid having at least one heteroatom containing substituent ortho, meta, or β of said carboxylic acid.
