Various functionalized unsymmetrical biaryls can be prepared in good t
o excellent isolated yields by palladium-catalyzed coupling reaction o
f aryl manganese chloride with aryl iodides, bromides or triflates. Th
e reaction takes place rapidly and cleanly under mild conditions by us
ing only 1% of palladium complexes. (C) 1997 Published by Elsevier Sci
