Abstract

Various mono-and disubstituted 2, 2'-bipyridines were synthesized in high yields and multigram scales utilizing Stille-type coupling procedures. The corresponding bromo- picoline and tributyltin-picoline building blocks were prepared from commercially available amino-picoline compounds. As first examples of metal complexes, 4, 5'-dimethyl-2, 2'- bipyridine was reacted with copper (II) and iron (II) ions and investigated as catalyst in ...
