Ligand-free Heck reactions using low Pd-loading.

Manfred T Reetz1, Johannes G de Vries.   

Abstract

Activated and non-activated aryl bromides undergo smooth ligand-less Heck reactions, provided low amounts of palladium salts such as Pd(OAc)2 are used (ideally 0.01-0.1 mol%). This industrially viable process appears to involve palladium nanoparticles.
