✦ Synopsis

The synthesis and properties of cationic complexes of general formula [ML2{CH2(Ph2PE)2}]BF4, where M = Pd H and Rh n, L2 = q3-MeC3H4, {P(O)(OR)z}EH (R = Me, Et), COD, (CO)z, (CO)PPh 3 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 Nail in THF, to give neutral complexes of the type [ML2{CH(Ph2PE)/}], where M = Pd ll, Rh~; L 2 = q3-MeCaH4, COD and E = S, Se. The complexes have been characterized by elemental analyses, molar conductivities, i.r., 1H n.m.r, and 31p{lH} n.m.r, spectroscopy.
