Abstract
The Heck arylation reaction of aryl iodides with allylic alcohols catalysed by an mesoporous silica (MCM-41)-supported bidentate nitrogen palladium complex [MCM-41-2N-Pd(OAc)2] proceeded smoothly in the presence of tetrabutylammonium chloride (TBAC) in DMF to afford β-aryl ketones in good to excellent yields. This heterogeneous palladium catalyst can be recovered by simple filtration and reused several times without any decrease in activity.
