For a long time, the Suzuki-Miyauracross-couplingreaction could not be used for the synthesis of 2,2′-bipyridines due to the lack of sufficiently stable 2-pyridylboron compounds. Stabilized 2-pyridylboronic acid esters recently developed by Hodgson, however, were found to be ideally suited for this purpose. Two general protocols could be developed and demonstrated to be valuable alternatives, which

Synthesis of Amino-Functionalized 2,2′-Bipyridines
Amino-functionalized 2,2′-bipyridines are versatile building blocks for the synthesis of sophisticated chelating ligands with the 2,2′-bipyridine core. The 4-, 5-, and 6-substituted 2-chloro- and 2-bromopyridine building blocks were prepared and coupled to symmetrically and non-symmetrically diamino-functionalized compounds by homo- and cross-coupling procedures. Further transformations were carried out to demonstrate the synthetic versatility of these compounds and the employed procedures.
