Oxidation of the aminophosphines with hydrogen peroxide, elemental sulfur and selenium gave the corresponding oxides, sulfides and selenides [Ph2P(E)](2)N-C6H4-C2H5 (E = O, S, Se). Complexes [MCl2{(Ph2P)(2)N-C6H4-(C2H5)}] (M = Pd, Pt) and [Cu{(Ph2P)(2)N-C6H4-C2H5)(2)]PF6 were obtained by the reaction of NN-bis(diphenylphosphino)ethylaniline with [MCl2(COD)] (M = Pd, Pt) and (Cu(MeCN)(4)]PF6. The new compounds were characterized by NMR, IR spectroscopy and microanalysis. In addition, representative solid-state structures of the palladium and platinum complexes were determined using single crystal X-ray diffraction analyses. (C) 2007 Elsevier Ltd.
