The synthesis of [FeRu(CO)2(μ-CO)2(η-C5H5)(η-C5Me5)] and convenient entries to its organometallic chemistry
Abstract
The synthesis, fluxionality and reactivity of the heterobimetallic complex [FeRu(CO)2(μ-CO)2(η-C5H5)(η-C5Me5)]
(5) are described. Complex 5 exhibits enhanced photolytic reactivity towards C(CO2Me)2}(η-C5H5)(η-C5Me5)]
(23) through an unusual methylcarboxylate migration. Protonation and then addition of

(25). Compound 25 exhibits cis/trans isomerisation at room temperature. Protonation of 11 gives the allenyl species [FeRu(CO)2(μ-CO)(μ-η1:η2-CH
C
CMe2)(η-C5H5)(η-C5Me5)][BF4]
(30). Compound 30 exist as three isomers, two cis and one trans. The two cis isomers are shown to be interconverting by σ–π isomerisation. The solid state structures of 5, 11, 12, 17, 23, 25 and 30 were established by
