The reaction of the heteronuclear cluster RuOs3(μ-H)2(CO)13 with saturated and unsaturated C5 rings led to the aromatization of the rings to afford the clusters RuOs3(μ-H)(CO)9(μ-CO)2(η5-C5R4R′). However, the reaction with cyclopentene gave the cluster RuOs3(μ-H)3(CO)11(μ,η1:η2-C5H7) via C–H activation of an sp2 carbon instead. Thermolysis of two of the products, RuOs3(μ-H)(CO)9(μ-CO)2(η5-Cp′) and
异核簇RuOs3(μ-H)2(CO)13与饱和和不饱和C5环的反应导致环芳构化,得到簇RuOs3(μ-H)(CO)9(μ-CO)2 (η5-C5R4R')。然而,与环戊烯的反应通过 sp2 碳的 C–H 活化得到了簇 RuOs3(μ-H)3(CO)11(μ,η1:η2-C5H7)。两种产物 RuOs3(μ-H)(CO)9(μ-CO)2(η5-Cp') 和 RuOs3(μ-H)(CO)9(μ-CO)2(η5-C5H4SiMe3) 的热解),导致它们异构化为蝴蝶簇。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
