Reaction of Diethylamine with 1-bromo-3-alken-3-ynes
In the reaction of 1-halogeno-3-buten-1-ynes with diethylamine the two reaction centers of the substrate enter into the reaction. The bromine at the sp-hybridized carbom atom is substituted, and the diethylamine adds the triple bond. 1,1-Bis(diethylamino)-1,3-alkadienes were isolated as the only products.
