PEG-400 Catalyzed Reaction for the Synthesis of 2, 4, 6-Triarylpyridines and Crystal Structure of 2,4,6-tris(4'-chlorophenyl)pyridine

An efficient and rapid procedure for synthesizing triarylpyridine compounds under mild reaction conditions has been described. Meanwhile, the crystal structure of 2,4,6-tris(4'-chlorophenyl)pyridine was obtained and determined by X-ray single-crystal diffraction. The procedure is operationally simple, giving good to high product yields.
