✦ Synopsis

Unsymmetrical biaryls bearing electron-donating and electron-withdrawing functional groups have been obtained in an efficient manner by Pd-catalyzed coupling of aryl halides. Aryl bromides react with aryl iodides to yield unsymmetrical biaryls with marked selectivity.

## Abstract Aryl bromides containing a (1,4,5,6‐tetrahydro‐6‐oxopyridin‐3‐yl)methyl substituent can be coupled with aryl halides yielding unsummetrical biaryls. In the course of this process, the cyclic enamide is oxidized to the 2(1__H__)‐pyridinone. The reaction proceeds by a six‐membered pallada
