| Popis: | The reaction of dichlorodicarbonylplatinum with ROOCC≡CCOOR (R = CH 3 , C 2 H 5 ) in benzene and toluene gives carbonylchloro(1,2- trans -dicarboalkoxy-2-chloroethenyl)platinum compounds by insertion of the active acetylene molecule into the Pt Cl bond. These chelated stable square-planar vinyl derivatives react with neutral donor ligands to give simple σ-alkenyl derivatives: [Pt(CO)Cl(ROOCC C(Cl)COOR)L] (L = C 5 H 5 N, CH 3 C 5 H 4 N), [PtCl(ROOCC C(Cl)COOR)L 2 ] (L = PPh 3 , PCH 3 Ph 2 ), and [PtCl(ROOCC C(Cl)COOR)(L L)] (L L = DPE, bipy, Me 2 bipy). The anionic species [ cis -Pt(CO)X 2 (ROOCC C(Cl)COOR)]− have been isolated as PPN salts by treating the vinyl complexes with Cl−, I− or SCN−. The stereochemistry has been elucidated from spectroscopic data (IR and 1 H NMR). |
