Fifteen symmetrical and asymmetrical dimethoxybipyridines and the pertinent diols are prepared and characterized.Reductive cross coupling of halopyridines with Ni(0) may result in complex mixtures.The same is true for an alternative reaction of (trimethylstannyl)pyridines with halopyridines in the presence of Pd(0).UV, 1H-, and 13C-NMR spectra of the bipyridine derivatives are tabulated.Key Words: Bipyridinediols / Pyridines / Stannylpyridines
Syntheses of Hydroxylated Bipyridines, II. - 3,4'-Dihydroxy-2,3'-bipyridine

The title compound 1 was obtained by coupling of 2-iodo-3-methoxypyridine (3) and 3-bromo-4-methoxypyridine (4) with Nickel (0) - to yield the dimethyl ether 2 (plus 5 and 6) - and by subsequent ether cleavage. 1 is not identical with the alkaloid described under this structure.
