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
