The structure of these heterocycles is confirmed by an X-ray analysis of 9d (R1 = ClC = CCl2, R2 = Et). p-Tolyl isocyanate is Friedel-Crafts alkylated by 4b in the presence of SbCl5. Subsequent ring closure affords the quinolinium salt 13, which is hydrolyzed to give inter alia the quinolone 16.</dcterms:abstract> <dc:contributor>Wang, Q.</dc:contributor> <dc:contributor>Troll, Carsten</dc:contributor> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:contributor>Fischer, Helmut</dc:contributor> <dc:creator>Al-Talib, Mahmoud</dc:creator> <dc:creator>Jochims, Johannes</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/23450"/> <dcterms:rights rdf:resource="https://kops.uni-konstanz.de/page/termsofuse"/> <dc:creator>Fischer, Helmut</dc:creator> <dc:contributor>Taha Abdel-Aal, M.</dc:contributor> <dc:language>eng</dc:language> <dcterms:issued>1992</dcterms:issued> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/29"/> <dc:contributor>Jochims, Johannes</dc:contributor> <dc:contributor>Hamed, A.</dc:contributor> <dc:creator>Taha Abdel-Aal, M.</dc:creator> <dcterms:title>On the Reaction of alpha,alpha-Dichlorocarbenium Ions with Isocyanates</dcterms:title> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/29"/> <dc:creator>Wang, Q.</dc:creator> <dc:creator>Hamed, A.</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-07-01T07:20:03Z</dcterms:available> <dc:creator>Zeid, Ibrahim</dc:creator> <dcterms:bibliographicCitation>Journal für praktische Chemie - Chemiker-Zeitung ; 334 (1992), 8. - S. 669-675</dcterms:bibliographicCitation> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> </rdf:Description> </rdf:RDF>
