โœฆ Synopsis

Synthesis of Functionally Substituted Unsymmetrical Biaryls via a Novel Double Metal Catalyzed Coupling Reaction.

-The coupling reaction is applicable to a variety of aryl halides, e.g. (I), (IV), (VI) and (IX), containing an activating group. The presence of Zn salts [ZnCl 2 , Zn(OAc) 2 ], ZnEt 2 or CdCl 2 as co-catalysts is essential for the reaction. -(MILLER, J.
