-phenyl-5,6-dihydro-1,2,4,5-tetrazinium) perchlorates (R = H, Me, Cl, OMe, CN, NO2) were obtained as a result of a three-stage synthesis from terephthalic aldehyde. The synthesis of tetrazinium salts was carried out by reaction of the corresponding formazans with formalin in the presence of perchloric acid in dioxane. Formazans and tetrazinium perchlorates were isolated in individual state and characterized
一系列 3,3'-(1,4-亚苯基)双(1-4-R-苯基)-5-苯基-5,6-二氢-1,2,4,5-四嗪鎓)高氯酸盐 (R = H、Me、Cl、OMe、CN、NO2) 是由对苯二甲醛三步合成得到的。四嗪盐的合成是通过相应的甲臜与福尔马林在高氯酸存在下在二恶烷中的反应进行的。甲臜和高氯酸四嗪以单独状态分离,并通过元素分析、IR、UV、1H 和 13C NMR 光谱数据进行表征。采用循环伏安法(CV)研究了高氯酸四嗪的电化学还原过程。已经表明,这些化合物是基于verdazyl自由基的对称双自由基系统的透视前体。
