| The promise of environmentally benign catalysts has lead to numerous investigations of solid-supported phosphine ligands. Nevertheless, reports of polymer-supported versions of the common ligands 1,2-bis(diphenylphosphinoethane) (dppe) and 1,2-bis (diphenylphosphinopropane) (dppp) have not yet appeared. We report the synthesis of bis(diphenylphospinomethyl)amine (dppa), a ligand structurally related to dppp, directly on amine-functionalized polystyrene (PS) synthesis beads. The characterization of the bead supported ligand both with and without complexed Ni(II) is also presented. |
