Abstract
In functionalized ionic liquid network of [BMIM][TPPMS] and [BMIM][OAc], PdCl2(CH3CN)2 efficiently catalyzed the Heck reaction of bromobenzene to ethyl cinnamate with yield of 60% and without the activity loss even after 11 recycling uses. The beneficial influences of this ionic liquid network on activity and stability were explained in terms of synergic ligand effects of [BMIM][TPPMS] and [BMIM][OAc], no accumulation of sodium or ammonium bromides by using [BMIM][OAc] as base, and the positive effect of [BMIM]Br by avoiding the formation of palladium black. The generality of this ionic liquid system to the different substrates also gave the pleasing results.
