《An improved synthesis of (hydroxymethyl)bipyridines》 was written by Smith, Adam P.; Corbin, Perry S.; Fraser, Cassandra L.. Formula: C12H10Cl2N2 And the article was included in Tetrahedron Letters on April 15 ,2000. The article conveys some information:
Quick and efficient syntheses of 4,4′-bis(hydroxymethyl)-2,2′-bipyridine and 4-(hydroxymethyl)-2,2′-bipyridine are described starting from 4,4′-dimethyl-2,2′-bipyridine and 4-methyl-2,2′-bipyridine, resp., via (trimethylsilyl)methyl-, bromomethyl-, and acetoxymethyl intermediates. After reading the article, we found that the author used 4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4Formula: C12H10Cl2N2)
4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. Formula: C12H10Cl2N2 Pyridine has a conjugated system of six π electrons that are delocalized over the ring.
