The corresponding hydrochlorides were obtained by the reaction of 2-vinyloxypyridine, 2-vinyl-oxylepidine, N-vinyl-2-pyridone, N-vinyl-2-lepidone, and 8-vinyloxyquinoline with hydrogen chloride.
Chlorine adds to the vinyl derivatives of hydroxypyridine and hydroxyquinoline predominantly across the double bond of the vinyl group, with the formation ofα,β-dichloroethyloxypyridines and pyridones. The reaction is accompanied by side processes.
