摘要
采用不同的氧化剂对ω - [5 - (1-苯基 - 5 -甲基 - 1,2 ,3-三唑 - 4 -基 ) - 4 -芳基 - 1,2 ,4 -三唑 - 3-硫基 ]-ω - (1H- 1,2 ,4 -三唑 - 1-基 )苯乙酮进行了氧化 ,结果发现 KMn O4 作为氧化剂时 ,氧化产物十分复杂 ,难于分离 ,而 H2 O2 - Ac OH及间氯过氧苯甲酸 (MCPBA)又不能将其氧化 ,最后采用 Na IO4 作为氧化剂时没有得到相应的砜或亚砜而意外得到 3-羟基 - 4 -芳基 - 5 - (1-苯基 - 5 -甲基 - 1,2 ,3-三唑 - 4 -基 ) - 1,2 ,4 -三唑衍生物 ,化合物的结构经元素分析和波谱确证 ,并对其生成机理作了初步讨论 .
A new method for synthesizing 3 hydroxy 4 aryl 5 (1 phenyl 5 methyl 1,2,3 triazol 4 yl) 1,2,4 triazole derivatives was described. When KMnO 4 was used as an oxidant, the oxidation products were so complex that they can not be separated. On the other hand, both H 2O 2 AcOH and MCPBA can not react with the sulfur ether. While NaIO 4 was used as an oxidant, no correspondent sulfones and sulfoxides were obtained but the title compounds. Elemental analysis and spectral data confirmed the structures of the new compounds. Mechanism of the oxidation reaction was also discussed.
