Abstract
1 - Dialkylamino - 4 - hydroxy - acetylenes - (2) of the formula <FORM:0895927/IV (b)/1> where R1 is hydrogen, methyl, ethyl, propyl or phenyl, R2 is hydrogen, methyl, ethyl or propyl, or R1 and R2 together form part of a cyclohexyl or cyclooctyl radical, R3 is methyl or ethyl, R4 is methyl or ethyl, or R3 and R4 together with the nitrogen atom represent a hydrogenated heterocyclic nitrogen- or nitrogen- and oxygen-containing radical, are prepared by reacting an aqueous solution or suspension of pH 3-6.8 of a salt of an amine R3R4NH in the presence of copper ions and at 40 DEG C.-100 DEG C. with formaldehyde and an a -hydroxyacetylenic compound <FORM:0895927/IV (b)/2>
