Synthesis of (Ph₃P)₂PdX₂ complexes and their catalytic activity for Heck reaction involving aryl halide and acrylate

Abstract

Two palladium complexes, (Ph₃P)₂PdBr₂ and (Ph₃P)₂PdI₂, were synthesized by a new method and their structures were confirmed by NMR, elemental analysis and X-ray crystallography. The catalytic activity of the two palladium complexes was evaluated in Mizoroki-Heck cross-coupling reaction of aryl halide with acrylate, the results show that they all have high catalytic activity to many different substrates.
