Convenient Synthesis of Some Styrylpyridinium Dyes Containing Methylenebis[benzenamine] Moiety

Abstract Condensation of 4-vinylpyridine with 4,4′-[(4-bromophenyl) methylene]bis[benzenamine] and its N-ethyl analogue adopting Heck's reaction yielded corresponding new styrylpyridines which were converted into their pyridinium bromides. All the compounds reported were characterized by analytical and spectral data.
