| Abstract: | Summary The synthesis and properties of cationic complexes of general formula ML2{CH2(Ph2PE)2}]BF4, where M = PdII and RhII, L2 = 
3-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 = PdII, RhI; L2 =
3-MeC3H4, COD and E = S, Se. The complexes have been characterized by elemental analyses, molar conductivities, i.r., 1H n.m.r. and 31P{1H} n.m.r. spectroscopy. |
