Aqueous dimethylamine has been found to add to vinylacetylene to give N, N-dimethyl-2, 3- butadienylamine which rearranges to N, N-dimethyl-2-butynylamine in the presence of excess dimethylamine or sodium methoxide. The structures of these amines have been established and other N-substituted-2, 3-butadienylamines also have been prepared by reactioii of vinylacetylene with aqueous methylamine, diethylamine, morpholine and n- ...
