Phosphanamine-functionalized magnetic nanoparticles (PAFMNP): an efficient magnetic recyclable ligand for the Pd-catalyzed Heck reaction of chloroarenes†
A phosphanamine-functionalized trimethoxysilyl compound (DPPPA) was synthesized and reacted with magnetic nanoparticles in order to synthesise a novel magnetic reusable phosphanamine ligand (PAFMNP) for application in transition metal-catalyzed coupling reactions. The Pd complex of PAFMNP (Pd–PAFMNP) was found to be an efficient heterogeneous catalyst for the Heck reaction of aryl chlorides. Only 1.0 mol% of catalyst was needed to accomplish the Heck reaction of the aryl chlorides. The catalyst was reusable at least 5 times without a significant decrease in its catalytic activity.
