In an aqueous alkaline medium dimethyl(β-halogenoethyl)ammonium salts containing a 2,3-unsaturated group undergo nucleophilic substitution with transfer of the reaction center in the six-membered ring with subsequent elimination of dimethylamine, forming intermediately an allylenamonium salt.They form the corresponding imines with high yields both when heated and at room temperature.
