ABSTRACT Thermal alkylation of trimethylphenacylammonium salt with dimethylphenylbenzylammonium salt (leucotropO) was carried out. α-Unsaturated ketone (chalcone) and the corresponding amine fractions were isolated as reaction products. It is assumed that benzylation takes place in the αC-of phenacyl group of Quat 1. The resulting quaternary ammonium salt immediately undergoes β-elimination under reaction conditions and is accompanied by the release of chalcone.
