Reusable Palladium N‑Heterocyclic Tetracarbene for Aqueous Suzuki–Miyaura Cross-Coupling Reaction: Homogeneous Catalysis and Heterogeneous Recovery

A pH-responsive Pd­(II) N-heterocyclic tetracarbene complex synthesized by a solvothermal method was reported. It can be a highly active reusable catalyst to homogeneously catalyze the Suzuki–Miyaura cross-coupling reaction in water and can be heterogeneously recovered by simply adjusting the pH value of the aqueous reaction media
