1,2,3-Triazolylpropanone was prepared and coupled with aryldiazonium salts yielding the corresponding arylhydrazones. Gas-phase pyrolysis of the hydrazono derivative produced N-arylamino-2-acetylimidazole as well as 2-acetylimidazole. The latter is the product of further pyrolysis of the former.
制备1,2,3-三唑基丙酮,并与芳基重氮盐偶联,得到相应的芳基hydr。肼基衍生物的气相热解产生了N-芳基氨基-2-乙酰基咪唑以及2-乙酰基咪唑。后者是前者进一步热解的产物。
