Abstract:Abstract-Monoalkylation of 1,4-dichlorobut-2-ene with prop-2-yn-1-ol under phase-transfer catalysis conditions led to the formation of 1-(prop-2-yn-1-yloxy)-4-chlorobut-2-ene. The latter reacted with dimethylamine to afford N,N-dimethyl-4-(prop-2-yn-1-yloxy)but-2-enyl-1-amine. Its quaternization afforded new ammonium salts containing 4-(prop-2-yn-1-yloxy)but-2-enyl group. Unsaturated tertiary amines formed as a result of Stevens 3,2-rearrangement of quaternary salts.
