A new synthetic route towards stable molecular‐weight enlarged monodentate phosphine ligands via ‘click’ chemistry was developed. These ligands were applied in the Pd‐catalyzed Suzuki–Miyaura coupling of aryl halides and phenyl boronic acid. The supported systems show very similar activities compared to the unsupported analogues. Moreover, recycling experiments by means of nanofiltration using ceramic nanofiltration membranes demonstrate that these systems can be recovered and reused efficiently.
