摘　　要：　本文合成了对甲苯磺酸铜,并应用热重(TG)和差示扫描量热法(DSC)进行分析.该铜盐容易脱除全部结晶水,且在空气中不潮解,如与乙醇胺形成等摩尔配合物,则在DMSO和DMF溶剂中能催化1,1′ 联 2 萘酚的氧化,但在H2O或CH3OH溶剂中则不发生反应.此外,还分别研究了该铜盐及其它铜盐与乙醇胺(1∶1)的配合物在DMSO、DMF、CH3OH和H2O中的电化学行为和催化活性.实验表明,铜胺配合物的两步单电子还原过程对催化氧化1,1′ 联 2 萘酚是必要的条件.Copper (II) paratolysulfate has been synthesized and characterized by thermo-gravimetric (TG) measurements and differential scanning calorimetric (DSC) analysis. This salt can easily lose all crystal water and the dehydrated salt does not deliquesce in the air. It is found for the first time that the complex of Cu(p-OTs)_(2)/ethanolamine(1∶1) can catalyze the oxidation of 1,1′-bi-2-naphthol in DMSO and DMF, while the process is difficult to perform in H_(2)O and CH_(3)OH. The electrochemical behaviors of both Cu(p-OTs)_(2) and its complexes with ethanolamine have been studied on platinum electrode in DMSO, DMF, (CH_(3)OH) and H_(2)O respectively. The complexes of various copper salts with ethanolamine are also studied by cyclic voltammetry in different solvents. It is concluded that the two one-electron steps are essential condition for the oxidation of 1,1′-bi-2-naphthol.
