Abstract
Abstract Iridium complexes prepared by reaction of binuclear 1,5-cycloocta-diene (COD) compounds of the type [IrX(COD) 2 ] (X = OMe, Cl) with monodentate Group Vb atom donor ligands (NPh 3 , PPh 3 , AsPh 3 , SbPh 3 ) yield a mixture of hexenyl(triethyl)silanes as well as the expected hexyl-(triethyl)silane from the catalytic hydrosilylation of hex-1-ene by triethyl-silane, in 1,2-dichloroethane at 60 °C. The most effective catalysts are those derived from [IrCl(COD)] 2 + 2 PPh 3 + 2 AsPh 3 and [Ir(OMe)(COD)] 2 + 2 As-Ph 3 . The latter system has been also found to be active for hydrosilylation reactions involving ethylene and propylene. The catalyst systems studied include [IrX(COD)] 2 + 2 L (X = OMe, L = NPh 3 , PPh 3 , AsPh 3 , SbPh 3 ; X = Cl , L = PPh 3 , AsPh 3 ), [Ir(OMe)(COD)] 2 + 4L (L = PPh 3 , AsPh 3 ) and [IrX(COD)] 2 + 2 PPh 3 + 2 AsPh 3 (X = OMe, Cl).
