Synthesis of a novel optically active C2-symmetric 2,2′-bipyridine was written by Bolm, Carsten;Ewald, Martina;Zehnder, Margareta;Neuburger, Markus A.. And the article was included in Chemische Berichte in 1992.SDS of cas: 6602-33-1 This article mentions the following:
Optically active 2,2′-bifuropyridine (S,S)-I was synthesized by radical cyclization and a nickel(0)-mediated coupling of enantiomerically pure bromopyridine (S)-II. Palladium, copper, and cobalt complexes of I were prepared The solid-state structures of meso–I and III were determined by x-ray crystal structure anal. In the experiment, the researchers used many compounds, for example, 2,6-Dibromo-3-hydroxypyridine (cas: 6602-33-1SDS of cas: 6602-33-1).
2,6-Dibromo-3-hydroxypyridine (cas: 6602-33-1) belongs to pyridine derivatives. Pyridine has a conjugated system of six 锜?electrons that are delocalized over the ring. The molecule is planar and, thus, follows the H鐪塩kel criteria for aromatic systems. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.SDS of cas: 6602-33-1
