Two isomeric heterobinuclear complexes (4xy and 4yx) are formed in the reaction of [(CO)5MC(NMe2)CCH] (1) with BuLi, [M‘(CO)6] (M ≠ M‘:  W, Mo, Cr), and CF3SO3CH3. 4xy and 4yx differ in the relative distribution of the metals M and M‘:  (4xy) and (4yx). The 4xy/4yx ratios obtained by the two different possible reaction sequences are similar. Complexes 4xy and 4yx do not interconvert. The reaction of cis-[(CO)4(Me3P)WC(NMe2)CCH] with BuLi, [W(CO)6], and CF3SO3CH3 likewise gives two isomers, (7) and (8). These results demonstrate the facile migration of carbonylmetal fragments along a carbon chain. The structures of the complexes 3b,c and 7 have been established by X-ray structural analyses.</dcterms:abstract> <dc:creator>Weibert, Bernhard</dc:creator> <dcterms:bibliographicCitation>Organometallics ; 21 (2002), 21. - S. 4425-4431</dcterms:bibliographicCitation> <dc:language>eng</dc:language> <dc:creator>Fuß, Bettina</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-06-05T06:59:06Z</dcterms:available> <dc:creator>Dede, Markus</dc:creator> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-06-05T06:59:06Z</dc:date> <dcterms:issued>2002</dcterms:issued> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/29"/> </rdf:Description> </rdf:RDF>
