    <dcterms:title>Supported cyclopentadienylmetal carbonyl complexes : III. Silica-gel-supported iron and cobalt derivatives</dcterms:title>
    <dcterms:abstract xml:lang="eng">Mononuclear cyclopentadienylcobalt carbonyl and cyclopentadienyliron carbonyl derivatives were covalently linked to a silica gel support either by reaction of (C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;5&lt;/sub&gt;O)Si(CH&lt;sub&gt;3&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt;C&lt;sub&gt;5&lt;/sub&gt;H&lt;sub&gt;5&lt;/sub&gt; or of (C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;5&lt;/sub&gt;O)&lt;sub&gt;3&lt;/sub&gt;SiC&lt;sub&gt;5&lt;/sub&gt;H&lt;sub&gt;5&lt;/sub&gt; with macroporous silica gel supported materials and subsequent treatment with Co&lt;sub&gt;2&lt;/sub&gt;(CO)&lt;sub&gt;8&lt;/sub&gt; or Fe&lt;sub&gt;2&lt;/sub&gt;(CO)&lt;sub&gt;9&lt;/sub&gt; or by reaction of (C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;5&lt;/sub&gt;O)Si(CH&lt;sub&gt;3&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt;C&lt;sub&gt;5&lt;/sub&gt;H&lt;sub&gt;4&lt;/sub&gt;Co(CO)&lt;sub&gt;2&lt;/sub&gt; and (C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;5&lt;/sub&gt;O)&lt;sub&gt;3&lt;/sub&gt;SiC&lt;sub&gt;5&lt;/sub&gt;H&lt;sub&gt;4&lt;/sub&gt;Co(CO)&lt;sub&gt;2&lt;/sub&gt; with a silica gel support. In contrast to their unsupported analogues, no bi- nuclear or polynuclear species are formed from the SiO&lt;sub&gt;2&lt;/sub&gt;-supported metal carbonyl derivatives even at temperatures up to 200°C. The cobalt derivative was found to be a catalyst for olefin hydroformylation reactions. Binuclear SiO&lt;sub&gt;2&lt;/sub&gt;-supported species are formed when [(C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;5&lt;/sub&gt;O)Si(CH&lt;sub&gt;3&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt;C&lt;sub&gt;5&lt;/sub&gt;H&lt;sub&gt;4&lt;/sub&gt;Fe- (CO)&lt;sub&gt;2&lt;/sub&gt;]&lt;sub&gt;2&lt;/sub&gt; or [(C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;5&lt;/sub&gt;O)&lt;sub&gt;3&lt;/sub&gt;SiC&lt;sub&gt;5&lt;/sub&gt;H&lt;sub&gt;4&lt;/sub&gt;Fe(CO)&lt;sub&gt;2&lt;/sub&gt;]&lt;sub&gt;2&lt;/sub&gt; are treated with a silica gel support. A large fraction of these surface-bound dimers are irreversibly converted into mononuclear hydridoiron carbonyl derivatives by hydrogen at elevated pressures.</dcterms:abstract>
