S. Sibille et al., AN EFFICIENT ROUTE TO UNSYMMETRICAL BIARYLS VIA THE ELECTROCHEMICAL PREPARATION OF FUNCTIONALIZED AROMATIC ZINC ORGANOMETALLICS, Synlett, (6), 1993, pp. 425-426
Various functionalized aromatic or heteroaromatic zinc organometallics
, which were prepared electrochemically from aryl chlorides or -bromid
es in the presence of a nickel-complex catalyst and zinc ions, reacted
with aromatic or heteroaromatic halides in the presence of catalytic
amounts of palladium phosphine complexes to give unsymmetrical biaryls
in good to excellent yields.
