A series of new stable ylides has been synthesized by the reaction of N-pyridinium salts with electrophiles such as carbon disulphide, isothiocyanate derivatives, phenylisocyanate and benzoylchloride in a two-phase system.Prepara

Reaction of N-pyridinium salts 2 with isothiocyanates results in a series of 3-(2'-benzimidazolyl)imidazopyridinium 2-thiolate derivatives 3 classified as conjugated mesomeric betaines.S-Methylation followed by deprotonation easily converts 3 into a new family of conjugated betaines 5.Semiempirical molecular orbital calculations provide complementary information to the X-ray analysis and experimental dipole moments of both betaines.
