REACTIONS OF N-HETEROAROMATIC CATIONS WITH JANOVSKY ANIONIC ? COMPLEXES

Article abstract of DOI:10.1007/BF00506107

Stable crystalline salts of anionic ? complexes and heteroaromatic cations were obtained as a result of exachange reactions of pyridinium, quinolinium, and isoquinolinium salts with the Janovsky anionic trinitrobenzene ? complex at room temperature.These salts are less stable with the dinitrobenzene ? complex and undergo decomposition upon heating with aromatization of the ? complex and ionic hydrogenation or nucleophilic alkylation of the heteroaromatic cations.A salt is not formed with the acridinium cation at room temperature; instead, the ? complex undergoesdehydroaromatization with subsequent addition of the acridinium cation to the resulting dinitrophenylacetone.
