A. Jouaiti et al., 3,3',5,5' TETRA(PHOSPHAALKENE) BIPHENYL - SYNTHESIS OF A NOVEL BICYCLOMETALATING BRIDGING LIGAND, AND STRUCTURE OF ITS DIPALLADIUM COMPLEX, Tetrahedron letters, 34(21), 1993, pp. 3413-3416
A biphenyl derivative bearing four phosphaalkene groups in positions 3
,3',5,5' has been synthesized and is shown to be a bis-terdentate chel
ating agent; this novel bridging ligand forms a complex with two palla
dium ions and the crystal structure of this dinuclear species has been
obtained.
