p ‐Benzenedisulfonic acid and 1,3,5‐benzenetrisulfonic acid are prepared in an efficient and scalable two‐step protocol from respective bromobenzene derivatives. These acids are used in analogy to terephthalic and trimesic acid for the formation of metal‐organic frameworks with copper(II) centers. Due to the enhanced acidity of sulfonic acids, weakly basic malachite can be used as inorganic precursor material. After dehydration at about 100 °C, the anhydrous frameworks exhibit significantly increased thermal stability (up to 400 °C) relative to the commonly known carboxylate MOFs.
