Eosin Y, an organic dye, was activated as a photoredox catalyst in the presence of molecular oxygen using visible light and, when it was used in the reaction of aryl ketones and benzyl amines, afforded good yields (52-87%) of 2,4,6-triarylpyridines (21 examples) at ambient temperature. The aryl groups at the 2- and 6-positions are derived from ketones, while benzyl amine plays the dual role of providing an aryl functionality at the 4-position of pyridine as well as being a nitrogen donor.

An industrial cadmium calcium phosphate catalyst was used in the syntheses of pyridine bases in the vapor phase by the Chichibabin method (condensation of carbonyl compounds with ammonia).Alkyl-substituted arylpyridines with the aryl radical at C2, C3, or C4 are formed during the condensation of aromatic aldehydes and ammonia with saturated and unsaturated aldehydes and also with methyl alkyl ketones.
