| Abstract: | Treatment of Ru2(CO)(μ-CO) {μ-C(O)C2Ph2} (η-C 5H5)2] with allene in toluene at 100°C displaces diphenylacetylene and produces Ru(CO)(η-C5H5)-{η3-C3H4Ru(CO)2(η-C5H5)}]; upon protonation a 1-methylvinyl cation Ru2(CO)2(μ-CO){μ-C(Me)CH2}(η-C5H5)2]+ is formed which undergoes nucleophillic attack by hydride to yield the μ-dimethylcarbene complex Ru2(CO)2-(μ-CO)(μ-CMe2)(η-C5H5)2]. |
