Abstract 4,4′‐Divinyl‐2,2′‐bipyridine (2) was prepared in 12% overall yield from 4,4′‐dimethyl‐2,2′‐bipyridine (3) via a 5 step reaction sequence involving the intermediate 4,4′‐R2‐2,2′‐bipyridines: R = COOH, 4; CO2CH3, 5; CH2OH, 6; CHO, 7. The newly synthesized compounds 2, 6 and 7 were characterized by melting point, infrared, 1H nmr, mass spectrometry and elemental analysis.
