Abstract
New quinolinium, isoquinolinium, and acridinium betaines were synthesized on the basis of chloroformyl-substituted azolinones and uracil. The peculiarities of their structures were examined by means of the UV and PMR spectroscopic data. It was established that the isoquinolinium betaine exists in the cyclic form.
