NOVEL CATALYST FOR ALDOL CONDENSATION REACTIONS

摘要

The present invention presents catalytic systems for aldol condensation reactions, comprising the step of reacting at least one aldehyde or one ketone starting material in the presence of an inorganic ammonium salt, or an aqueous or organic solution prepared from such salt. The efficiency of the catalytic system of the present invention is comparable to those of the classical strong acid and strong base catalysts.
