the heteropentalenes5H-pyrazolo[1′,2′:1,2]-1,2,3-triazolo[5,4-a]phenazinyliumide (1) and 1,3-dimethyl-5H-pyrazolo[1′,2′:1,2]-1,2,3-triazolo [5,4-a]phenazinyliumide (2) are discussed. The u.v. absorption spectra of the free and of the protonated from are reported. Catalytic hydrogenation at room temperature reduces the C-6–C-7 double bond so that the loss of aromaticity is minimized. Compound (2) is
杂戊酮5H-吡唑并[1',2':1,2] -1,2,3-三唑并[5,4- a ]苯并氮杂(1)和1,3-二甲基-5H-吡唑并[1]的一些性质讨论了',2':1,2] -1,2,3-三唑并[5,4- a ]苯甲腈(2)。报告了游离和质子化的的紫外吸收光谱。在室温下进行催化加氢会还原C-6–C-7双键,从而使芳族化合物的损失降至最低。化合物(2)在室温下被过酸氧化,攻击位置12b的碳原子(在该杂戊烯的“偶氮甲基亚胺化物”结构中带负电荷)并形成醌亚胺。
