Abstract
The addition of bromine to vinyl derivatives of 2-hydroxypyridine, 2-hydroxylepidine, and 8-hydroxyquinoline was studied. The behavior of the compounds differs as a function of the structure and the position of the vinyl group attached to the oxygen or nitrogen of the pyridine ring. A complex involving the unshared electron pair of the nitrogen atom is obtained with 2-vinyloxypyridine and bromine. N-Vinyl-2-pyridone and 2-vinyloxylepidine add bromine primarily at the double bond of the vinyl group. This reaction proceeds in a more complex fashion with N-vinyl-2-lepidone and 8-vinyloxyquinoline. The structures of the synthesized compounds were investigated by means of IR and PMR spectra.
