    PREPARATION AND PROPERTIES OF PALLADIUM(II) AND RHODIUM(I) COMPLEXES CONTAINING BIDENTATE PHOSPHINE SULFIDE AND SELENIDE LIGANDS
    (1993) CONTRERAS, R; VALDERRAMA, M; YANEZ, S
    The synthesis and properties of cationic complexes of general formula (ML2{CH2(Ph2PE)2)]BF4, where M = Pd(II) and Rh(II), L2 = eta3-MeC3H4, {P(O)(OR)2}2H (R = Me, Et), COD, (CO)2, (CO)PPh3 and E = S, Se are described. The methylene proton of the coordinated phosphine sulphide or selenide ligands react with strong bases as BuLi in n-hexane or NaH in THF, to give neutral complexes of the type [ML2{CH(Ph2PE)2)], where M = Pd(II), Rh(I); L2 = eta3-MeC3H4, COD and E = S, Se. The complexes have been characterized by elemental analyses, molar conductivities, i.r., H-1 n.m.r. and P-31{H-1} n.m.r. spectroscopy.
