Abstract A convenient method for the synthesis of 2-aryl-1-methylquinolin-4(1 H )-ones is described. Spectroscopic and X-ray crystallographic techniques as well as quantum chemical calculations have been used to probe the structure of potentially tautomeric 2-arylquinolin-4(1 H )-ones in solution phase, gas phase and solid state. The exclusive NH-4-oxo nature of the title compounds in solution phase
摘要 描述了一种合成 2-芳基-1-甲基喹啉-4(1 H)-酮的简便方法。光谱和 X 射线晶体学技术以及量子化学计算已被用于探测溶液相、气相和固态中潜在互变异构的 2-芳基喹啉-4(1 H)-酮的结构。通过将它们的光谱数据与相应的 2-芳基-1-甲基喹啉- 4(1 H)-酮和2-芳基-4-甲氧基喹啉衍生物。质谱分析的结果证实了气相中 4-喹啉酮和 4-羟基喹啉异构体的共存,这得到了量子化学计算的支持。
