Tertiary amines and quaternary salts derived from alpha-substituted stilbenes and heterocyclic nitrogen bases

N-bromosuccinimide and -methylstilbenes, p-methyl--chlorostilbene, and p-methyltolan give bromomethyl derivatives, which react with piperidine to give tertiary amines. The latter and methyl iodide give quaternary salts.With pyridine, -picoline, and quinoline, the p-bromomethyl-d-chlorostilbenes synthesized give quaternary bromides which are readily soluble in water and converted into perchlorates by KClO₄.
