1-arylamino-1,2,3-triazole derivatives via diazo transfer reaction on active methylene hydrazones. Further, we have observed the reduction of 1-arylamino-1,2,3-triazole using Pd/C, H2 to result in unusual N-N bond cleavage to give 4,5-disubstituted-1H-1,2,3-triazole.
在这篇通讯中,作者描述了通过活性亚甲基腙上的重氮转移反应合成 1-芳基氨基-1,2,3-三唑衍生物。此外,我们还观察到使用 Pd/C, H2 还原 1-芳基氨基-1,2,3-三唑,导致不寻常的 NN 键断裂,得到 4,5-二取代-1H-1,2,3-三唑。
