Abstract

The reaction of the heteronuclear cluster RuOs₃(u-H) ₂(CO)₁₃ with saturated and unsaturated C₅ rings led to the aromatization of the rings to afford the clusters RuOs ₃(u-H)(CO)₉(μ-CO)₂(η⁵-C ₅R₄R′). 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(η ⁵-Cp′) and RuOs₃(μ-H)(CO)₉(μ-CO) ₂(η⁵-C₅H₄SiMe₃), led to their isomerization to butterfly clusters.
