A novel Pd(II) organometal catalyst with three‐dimensional (3D) cage‐like Ia3d cubic mesoporous structure and high surface area was prepared. In comparison with the corresponding catalyst with two‐dimensional (2D) P6mm hexagonal mesoporous structure, the as‐prepared catalyst exhibited higher activities in the water‐medium Suzuki coupling reactions owing to the diminished diffusion limit. It showed comparable efficiencies with the Pd(PPh 3 ) 2 Cl 2 homogeneous catalyst and could be easily recycled and reused for five times without significant loss of activity.
