Summary:beta -Dicarbonyl, beta -cyanocarbonyl and beta -dicyano compounds I I where R1 is an organic radical, X and Y are COOR2, -CO-R2 or -CN and R2 is an organic radical, are prepared from R1-CHO (II) and X-CH2-Y (III) by reaction in the presence of a condensation catalyst, hydrogen and a hydrogenation catalyst, using an oxide or phosphate of Mg, Al, Ti, Zn or a rare earth metal as the condensation catalyst.
