The reactions of Cu(II) with 6,7-dimethyl-5,6,7,8-tetrahydropterin dihydrochloride (H4DMP·2HCl) in CH3OH-CH3CN have been investigated by spectroscopic methods. The redox reaction in the 1 : 1 Cu(II)–H4DMP·2HCl system has been established by detection of the protonated trihydropterin radical (H4DMP•+) and its disproportionation products.
用光谱方法研究了 Cu(II) 与 6,7-二甲基-5,6,7,8-四氢蝶呤二盐酸盐 (H4DMP·2HCl) 在 CH3OH-CH3CN 中的反应。通过质子化三氢蝶呤自由基(H4DMP•+)及其歧化产物的检测,建立了1:1 Cu(II)-H4DMP·2HCl体系中的氧化还原反应。
