Über die Bildung eines neuen, stark fluoreszierenden Heterocyclus bei der versuchten Quarterinisierung von Chinolin

摘要

When quinoline is treated with ethyl bromoacetate in ethanol at a molar ratio of 1.5:1, a highly fluorescent pyrrolodiquinolinium ion (2a) is formed along with quarternized quinoline (1a). The structure of2ahas been established by infrared, proton magnetic resonance and mass spectroscopy as well as by its characteristic ultraviolet absorption spectrum.
