3-dimethylbutan-2-onyl-substituted dimethylammonium salts containing prop-2-ynyl, but-2-ynyl or 3-phenylprop-2ynyl group underwent 3,2-Stevens rearrangement by the action of basic agents to form allenic aminoketones [4]. In the case of the salts containing ethyl, propyl or butyl group instead of methyl moiety the products of both 3,2and 1,2-Stevens rearrangement were obtained. The 3,2-rearrangement product

Ammonium salts bearing but-2-ynyl and phenacyl or 2-(naphth-2-yl)-2-oxoethyl moieties at the nitrogen atom underwent Stevensrearrangement to form substituted furan-3-amines. Quaternization of the latter afforded appropriate iodomethylates.
