Heterogeneous or Homogeneous? A Case Study Involving Palladium‐Containing Perovskites in the Suzuki Reaction

The utility of a series of palladium-containing perovskite catalysts in the Suzuki reaction is described; turnover numbers of up to 400,000 are reported. A detailed investigation into the mode of action of these catalysts encompassing kinetic studies, catalyst poisoning, microscopy and three-phase tests demonstrate that these heterogeneous materials are pre-catalysts that operate by a solution-phase mechanism
