The multi-dentate ligands and their complexes have attracted more and more interests in supramolecular chemistry and catalysis.[1,2] Recently, we found a convenient and efficient method to synthesize this kind of P,N-ligands. The C-Hor C-Cl bond in N-heterocycle was activated in presence of corresponding organophospine reagent and the HCl elimination was fluent, giving the multi-dentate P,N-ligands.……
