Abstract

An efficient and one-pot synthesis of 2,4,6-triarylpyridines by palladium-catalyzed cyclocondensation of benzaldehydes, terminal aromatic alkynes and ammonium bifluoride in the presence of tert-butyl peroxide (TBP) as oxidant is developed.

Keywords: Aromatic alkyne, ammonium bifluoride; benzaldehyde, cyclocondensation, triarylpyridines.
