The process for preparing alkynediols of the formula (I)whereR1, R2 are each independently H, or a C1-20-hydrocarbon radical which may be substituted by one or more C1-6-alkyls and/or be interrupted by nonadjacent heteroatoms and/or contain C-C double or triple bonds,by reacting compounds of the formula (II)with acetylene in a polar aprotic solvent is carried out in the presence of basic alkali metal salts as catalysts.
