摘要

A convenient method for the synthesis of 2-aryl-1-methylquinolin-4 (1H)-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 (1H)-ones in solution phase, gas phase and solid state. The exclusive NH-4-oxo nature of the title compounds in solution phase (NMR) and solid state (IR and X-ray) is also ...
