Abstract

Abstract The consumable anode process allows the electrochemical preparation of arylzinc compounds in the presence of cobalt chloride as catalyst in a mixed solvent acetonitrile/pyridine (9: 1). Conjugate addition of these organometallic reagents to olefins is also obtained in good yields via a new method using CoBr 2 (2, 2′-bipyridine) 2 as catalyst.
