Abstract: | The platinum(II) ylids X2Pt{CH(py)CH2CH3}(py)] (X = Cl, Br; PY = pyridine) react with carbon monoxide to give the platinum carbonyls CO(X2)Pt{CH(py)CH2CH2CH3}] which lose CO on heating or in solution. The platinum(IV) ylids Cl4Pt{CH(py)CH2CH3}(py)] andCl2I(CH3)Pt{CH(py)CH2CH3}(py)] also react with CO to give Pt(CO)-ylid compounds. |
