Abstract: The invention relates to a method for producing alkapolyenyl compounds by effecting the homogeneously catalyzed reaction of 1-substituted alka-2,7-dienes of formula (I) and/or of 3-substituted alka-1,7-dienes of formula (II), in particular, octa-2,7-dienylethers, in the presence of rhodium compounds, whereby at least one mineral acid and/or at least one inorganic halogenide is dissolved in the reaction mixture. In this method, mineral acids and/or inorganic halogenides are used as cocatalysts which are dissolved in the reaction mixture. The products which are produced by using the inventive method are used as intermediate products in the production of surface-active materials.
