Double nucleophilic addition of carbon donors to [(benzene)(arene)Ru]2+ cations
Abstract
The nucleophiles MeLi and PhLi add cleanly to both rings in [(η6-C6H6)(η6-arene)Ru]2+(arene = C6H6, C6H3Me3, C6H3Pri3, C6Me6) to yield bis(η5-cyclohexadienyl) complexes; [(η4-cyclohexadiene)(arene)Ru] complexes are not formed.
