Abstract: The palladium-catalyzed direct 1,4-addition of arylhalides to
   a,beta-Unsaturated ketones was in-vestigated. It was found that
   Pd(PPh_3)_4 exhibited the highest catalytic activity to give the desired
   1,4-addition products in satisfactory yields. The present method avoids
   the use of expensive N-heterocyclic carbene ligands and organometallic
   reagents,and has advantages of high selectivity and ease of opera-tion.
