-
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.
