中文摘要 | 在3-芳香基-3H-1,3,4-�x二唑-2-酮(1)類化合物與一級胺類化合物的反應中,我 們可以得到不錯產率的 2- 芳香基 -4- 取代基 -2,4- 二氫 -3H-1,2,4- 三唑 -3- 酮 (2) 類化合物,其結構可由 X-ray 加以證實;然而,當 (1) 與水合胼進行反應時,在反應中會 伴隨著另一個卡胼類化合物的生成,對於此卡胼類化合物的結構亦可由 X-ray 加以證實。 |
英文摘要 | It has been found that 2-ary1-4-substituted-3H-1,2,4-triazol-3-ones can be generated by reactions of the title compounds with a series of primary amines. The products were confirmed by X-ray structures and the yields were in the range 75-90%. More significantly, utilizing of hydrazine hydrate as starting material, carbazides wer able to be synthesized and accompanied with 2-aryl-4-substituted-3H- 1,2,4-triazol-3-ones at various ratios. In the latter reaction, the X-ray crystal structures of both products wer again successfully obbtained. |
