Treatment of an amide with an alkyl or substituted alkyl halide in the presence of a weak base in a one-pot reaction leads to crystalline quaternary ammonium halides with reasonable chemical yields; some of the compounds show low melting points and a liquid range of over 50–100 °C before decomposition.
在弱碱存在下,将酰胺与烷基或取代烷基卤化物进行一锅反应,可得到结晶的季
铵卤化物,且
化学收率合理;其中一些化合物的熔点较低,分解前的液态范围超过 50-100 °C。
