摘要
Synthesis of 2-ethylhexyl-4-methoxy cinnamate was carried out efficiently using palladium-catalyzed Heck reaction of 4-bromoanisole and 2-ethylhexylacrylate in tetrabutyl ammonium bromide-based ionic liquid. The ionic liquid was used as a cost,effective reaction medium and the catalyst in it is Stable and Can be recycled for at least four times Without significant lass in activity.
