Synthesis of the Unsaturated Diamines by the Stevens Rearrangement of 4-Diethylaminobutyn-2-yl-Containing Ammonium Salts

摘要

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.
