The development of new methods for the synthesis of 2,4,6-triarylpyridines is an impor- tant area of research because of the broad spectrum of their biological and pharmaceutical properties such as anti-covulsant, anesthetic, anti-malarial, vasodilator, anti-epileptic character and their use as pesticidial, fungicidal and herbicidal agro-chemicals. 1–3 Due to their p-stacking ability, some pyridines are used in supramolecular chemistry. 4–7 The 2,4,6-triarylpyridine nucleus is structurally related to symmetrical triarylthio-, triarylse- leno- and triaryltelluoropyrylium salt photosensitizers and has been recommended for photodynamic cell–specific cancer therapy
