Highly Ordered Mesoporous Polymer‐Supported Phosphine as the Ligand for Organometallic Reaction: Suzuki‐Miyaura Cross‐Coupling of Aryl Chlorides at Room Temperature.

We prepared a highly ordered mesoporous polymer‐supported diarylphosphine ligand by simple substitution reaction. By utilizing this ligand, we successfully achieved the Suzuki‐Miyaura cross‐coupling of various aryl chlorides at room temperature with high yields. Also, we extended our investigation to the use of a macroporous polymer support in a similar way, which yielded effective Suzuki‐Miyaura cross‐coupling reactions of both aryl chlorides and hindered aryl bromides.
