Amines and Ammonium Compounds: CCXXXI. Synthesis of Tertiary Allenic 1,5-Diamines

Dialkylammonium salts containing both 4-penten-2-ynyl and 2-propynyl groups react with aqueous secondary amines to give 1,5-bis(dialkylamino)penta-2,3-dienes. Optimal reaction conditions are found and a mechanism of elimination of the 2-propynyl group from the initial salts is proposed.
