Ammonium salts containing 4-diethylaminobutyn-2-yl and 2-alkenyl groups undergo the Stevens 3,2-rearrangement under the action of potassium hydroxide in anhydrous benzene to form the unsaturated diamines.

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
