Abstract: The reaction of the heteronuclear cluster [Cp*IrRu 3(μ-H)2-(CO)10] (1) with the symmetrical alkynes RCCR (R = Ph, Et) afforded the butterfly clusters [Cp*IrRu 3(CO)9(RCCR)] (2) and the trinuclear clusters [Cp*IrRu2(CO)7(RCCR)] (3) and [Ru 3(CO)8(C4R4)] (4). The clusters 2 and 3 have the alkyne aligned parallel to an Ru-Ir bond. The reaction of 1 with unsymmetrical alkynes also afforded stereoselective binding of the alkyne such that the bulkier substituent was pointing away from the Cp*Ir moiety; with PhCCH, however, all three stereoisomers were obtained. With the bis-silylated alkynes (R = SiMe3, SiEt3), loss of one trialkylsilyl group occurred to give [Cp*IrRu3(CO)9(HCCR)] and [Ru3(CO)9(μ-H)(CCR)] (5). © Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
