Synthesis of a new C3-symmetric tripodal P4-tetradentate ligand and its application to the formation of chiral metal complexes

Article abstract of DOI:10.1021/om900923t

A novel C₃-symmetric tetradentate tripodal ligand with phosphorus as coordinating atoms has been synthesized in good yields. Its coordination ability through the four phosphorus atoms, three at the arms and one at the bridging position, is shown by formation of rigid Pd(II) and Rh(I) complexes. These C₃-iymmetric complexes are intrinsically chiral; experimental evidence for their configurational stability is included.
