Ten aromatic building blocks (8–11, 23–28) containing phosphonic and sulfonic acid groups within one molecule were synthesized. Twofold nucleophilic substitution starting from 1,2,4,5-tetrakis(bromomethyl)benzene (1) followed by hydrolysis gave building blocks 8–11. To obtain building blocks 23–28, the respective bromobenzenesulfonic acids 13, 16, 18–20 and 22 had to be synthesized first. Palladium-catalysed
十个芳香族积木(8-11,23-28一个分子中含有膦基和磺酸基)的合成。从1,2,4,5-四(溴甲基)苯(1)开始两次亲核取代,然后水解得到结构单元8-11。为了获得积木23-28,各个bromobenzenesulfonic酸13,16,18-20和22必须首先合成。钯催化的与亚磷酸三乙酯的交叉偶联,然后水解,得到了具有膦酸和磺酸基团的所需结构单元。积木9该化合物成功地用作合成具有组成[La 2(H 2 L)1.5(H 2 O)4 ]的新型La基CP的连接基。
