carboxamides and carbamates with ammonium hexanitratocerate(IV) or ferrocenium hexafluorophosphate generates their N-acyliminium ions by the elimination of tributylstannyl radical under mild reaction conditions. The iminium ions thus formed react with various carbon nucleophiles to give the corresponding addition products.
