Abstract
The reactions of δ-bromoketones 1 with amines lead to cyclic enamines 6 or secondary δ-am inoketones 3 depending on the nature of the amine used. Amino substituents which increase the nucleophilicity forces the course of the reaction towards cyclisation to 6 , which in turn yields the corresponding iminium salts 5. This pathway can be suppressed by large substituents leading to the formation of ammonium salts 4.
