dc.description.abstractA new method for the preparation of N-acyliminium salts 3a-ab by reaction of nitrilium salts 1 with non-enolizable alkyl and aryl ketones 2 is described. 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.eng
