4-benzenedisulfonic acids by exploiting crystallization of the barium salts and their subsequent protonation with cation-exchange resin was developed. This technique was applied to the preparation of 2-chloro-, 2-bromo-, 2-iodo-, and 2-hydroxy-1,4-benzenedisulfonic acids. The iodo derivative was submitted to Suzuki coupling reactions with Pd/C as the catalyst, and the respective biphenyl derivatives were
通过利用钡盐的结晶及其随后与阳离子交换树脂的质子化,开发了 2-取代的 1,4-苯二磺酸的制备、分离和纯化方案。该技术用于制备 2-氯-、2-溴-、2-碘-和 2-羟基-1,4-苯二磺酸。碘衍生物以 Pd/C 为催化剂进行 Suzuki 偶联反应,随后分离出相应的联苯衍生物。制备碘二磺酸的铜(II)盐。在固态下,它被发现形成聚合物链,在二维层中互锁。发现该材料在高达 400°C 的温度下是热稳定的,在该温度以上,盐分解生成 CuI。
