Synthesis, structures and properties of phosphine-substituted platinum carvonyl clusters

Abstract

The direct reduction and carbonylation of Pt(PPh3)2Cl2 with CO in aqueous NaOH solution was studied. At 40-50? a mixture of Pt3(m2-CO)3(PPh3)4, Pt3(m2-CO)3(PPh3)3(I), Pt(Cl)(PPh3)2(CO2Me)(II) and Pt4(m2-CO)5(PPh3)4 was obtained. At 10-15? a mixture of I, II and Pt5(m2-CO)5(CO)(PPh3)4 was obtained. The structures of I and II were determine by x-ray diffraction anal. and mass spectra.
