Abstract: A number of methods have been developed for the preparation of pyridinium ylides of mesomeric sixmembered heterocycles. According to the formula scheme the quinoline derivative 2 was obtained. Pyridine derivatives such as isoquinoline or nicotineamide give similar ylides. The best yields were obtained from the compounds 4 and 6.
