SYNTHESIS OF SOME NEW ASYMMETRICAL AND SYMMETRICAL 2,4,6-TRIARYLPYRIDINES USING (2-THIOPHENOYLMETHYLENE)PYRIDINIUM YLIDE.

A series of some new 2-thienyl-4,6-di(substituted phenyl)pyridines and 2,6-dithienyl-4-(substituted phenyl)pyridines have been synthesized by the interaction of (2-thiophenolymethylene)pyridinium ylide with substituted benzylideneacetophenones and substit

Synthesis of Some New 2,4,6-Triarylpyridines Using Phenacylpyridinium Ylid

Phenacylpyridinium ylid reacts with some substituted benzylidene-2-acetothiophenes, benzylidene-4-chloroacetophenones and benzylidene-3-nitroacetophenones in the presence of ammonium acetate in methanol or glacial acetic acid to give 2-phenyl-4-substituted-phenyl-6-(2-thienyl)pyridines (5a-e), 2-phenyl-4-substituted-phenyl-6-(4-chlorophenyl)pyridines (5f-j) and 2-phenyl-4-substituted-phenyl-6-(3-nitrophenyl)pyridines (5k-m), respectively in fair to good yields.
