Abstract

Nucleophilic substitution of 4-(dimethylamino) pyridine on pentachloropyridine yielded pentakis (pyridine-2, 3, 4, 5, 6-pentayl) pyridinium, tris-(3, 5-dichloropyridine-2, 4, 6-triyl) pyridinium, or (tetrachloropyridin-4-yl) pyridinium depending on the reaction conditions. Nucleophilic substitution with water, hydroxides, and alcoholates resulted in new betaines and highly substituted pyridines.
