The reactions of two atacetylenicdsmines,(CH&C (N&)-C= CH, were studied in detail. These compounds, 3-dimethylamino-3-methyl-1-butyne and 3-pyrrolidino-% methyl-l-butyne, were found to undergo the typical reactions of the triple bond and of the ethynyl hydrogen. From the two model compounds, twenty-six new substances of the following classes were prepared: scetylenic-1, 4-amino alcohols, C-alkylated acetylenic amines, acetylenic-l, ...
