Abstract
The efficient and convenient synthesis of various functionalized 4-phenyl-pyridines 2 is described. The key step of the procedure is the electrochemical formation of aromatic organozinc reagents 1 and their coupling with pyridinium salts. Intermediate 1, 4- dihydropyridines are oxidized using mild conditions to provide functionalized 4-phenyl- pyridines in moderate to high overall yields.
