✦ Synopsis

Synthesis of New Conjugated Mesomeric Betaines from Alkoxycarbonylazinium Salts.

-Treatment of the iodide (I), which is generated from 2-ethoxycarbonylpyridinium N-aminide, with aminoheterocycles leads to various mesomeric betaines like (III) and (VI). In some cases, however, desired betaines are not formed but associates like (VIII) arising from strong hydrogen bonding interactions. -(VALENCIANO,
