    Heterodinuclear PtRh and PtIr complexes with phosphinite groups as bridging ligands
    (1998) Contreras, R; Valderrama, M; Moscoso, R
    Compounds of the general formula [Pt(eta(2)-L) {P(O)Ph-2}{P(OH)Ph-2}], where eta(2)-L = {eta(2)-S2P(OEt)(2)}(-) (I) and {eta(2)-(SCNEt2)-C-2}(-) (2), react in THF solution with the dinuclear complex [{(cod)M(mu-OMe)}(2)] (M = Rh-I or Ir-I) to give new heterodinuclear compounds of the type [(eta(2)-L)Pt{mu-P(O)Ph-2}(2)M(cod)], where eta(2)-L = {eta(2)-S2P(OEt)(2)}(-); M = Rh-I (3), Ir-I (4) and eta(2)-L = {eta(2)-S2C-NEt2}(-); M = Rh-I (5) and Ir-I (6). Compounds (3) and (4) react with an excess of CO, leading to displacement of the coordinated pi-diolefin (cod) and the formation of the dicarbonyl derivatives [{eta(2)-S2P(OEt)(2)}Pt{mu-P(O)-Ph-2}(2)M(CO)(2)] [M = Rh-I (7), Ir-I (8)].
