Abstract

The reaction of the heteronuclear cluster RuOs~3~(μ‐H)~2~(CO)~13~ with saturated and unsaturated C~5~ rings led to the aromatization of the rings to afford the clusters RuOs~3~(μ‐H)(CO)~9~(μ‐CO)~2~(η^5^‐C~5~R~4~R′). However, the reaction with cyclopentene gave the cluster RuOs~3~(μ‐H)~3~(CO)~11~(μ,η^1^:η^2^‐C~5~H~7~) via C–H activation of an sp^2^ carbon instead. Thermolysis of two of the products, RuOs~3~(μ‐H)(CO)~9~(μ‐CO)~2~(η^5^‐Cp′) and RuOs~3~(μ‐H)(CO)~9~(μ‐CO)~2~(η^5^‐C~5~H~4~SiMe~3~), led to their isomerization to butterfly clusters.(© Wiley‐VCH Verlag GmbH & Co.
