Abstract

Unsymmetrical biaryls may be prepared in an efficient manner using aryl chlorides as substrates in Negishi-type cross-coupling reactions with arylzinc reagents via either Ni-or Pd- catalysis. Since a wide range of functional groups (eg, nitrile, carbonyl, ester) tolerate arylzinc compounds, this methodology allows for the direct synthesis of biaryls from aryl chlorides possessing these moieties.
