Stille-Type Cross-Coupling – An Efficient Way to Various Symme¬trically and Unsymmetrically Substituted Methyl-Bipyridines: Towards new ATRP Catalysts

Schubert, Ulrich S.; Eschbaumer, Christian; Heller, Marcel

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 ATRP.
