Ketones without electron-releasing substituents react only with N-arylnitrilium salts 1. An X-ray structural analysis was carried out for the N-acyliminium salt 3j. From variable temperature NMR spectroscopy intramolecular conformational changes (essentially rotation around the iminium C=N double bond, coupled to rotation about the amide C-N single bond) of few compounds 3 were determined. The observed barriers to hindered rotation are compared with barriers calculated by the AM1 method.</dcterms:abstract> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:contributor>Al-Talib, Mahmoud</dc:contributor> <dc:contributor>Fischer, Helmut</dc:contributor> </rdf:Description> </rdf:RDF>
