The course of the reaction of amines with (acy1oxy) alkyl a-halides has been found to depend on the nucleophilicity of the amines and the leaving group ability of the halides. More nucleophilic amines tended to give acylated products 2 from the reaction while less nucleophilic amines gave alkylated produds 3. The use of a better leaving group also tended to favor the formation of a greater amount of alkylated product. These results have ...
