摘要

The Heck reaction of aryl halides with terminal olefins was successfully performed by using Pd (OAc)(2) as the catalyst in a ligand-free PEG(1000)-DIL (PEG(1000)-based dicationic ionic liquid)/toluene system exhibiting temperature-dependent biphasic behavior. In addition, the isolation of the products is readily performed by a simply decantation, and the catalytic system can be recycled and reused without loss of catalytic activity.
