Recent Advances in the Heterogeneous Palladium-Catalysed Suzuki Cross-Coupling Reaction

The Suzuki cross-coupling reaction, which is commonly referred to simply as the Suzuki reaction and uses palladium as a catalyst, has become an efficient tool for constructing C-C bonds over the past two decades. This paper reviews recent advances in the use of this reaction with heterogeneous palladium catalysts. The heterogenization of homogeneous catalysts by incorporation into an inorganic support (silica, mainly) or an organic polymer is currently of one the hottest research topics. Although heterogeneous catalysts based on uncomplexed Pd(II) or Pd(0) deposited on an inorganic supports such as carbon, silica or a zeolite remain in wide use, new catalysts consisting of Pd(0) nanoparticles entrapped in or deposited onto an organic or inorganic support are being increasingly used in the Suzuki reaction.
