Preparation of Some Substituted Terephthalic Acids

Abstract

We report in detail the preparation of two substituted terephthalic acids: 2‐sulfomethylterephthalic acid (1) and 2‐phosphonoterephthalic acid (2). Efficient, short syntheses have been developed for both compounds. They are potentially useful monomers for construction of acid‐pendant polymer chains.

Keywords:

• Acid‐pendant polymers
• arenephosphonic acids
• arenesulfonic acids
• terephthalic acids
