Use of a solid hydrotalcite structure incorporating fluorides for basic catalysis of michael or knoevenagel reactions

摘要

The invention concerns the use of a solid basic catalyst comprising a hydrotalcite structure wherein part at least of the compensating anions are fluoride anions F⁻ for producing Knoevenagel of Michael condensation reactions. The invention also concerns novel solid basic catalysts comprising a hydrotalcite structure characterised by a Mg/Al molar ratio ranging between 2.5 and 3.8 wherein at least part of the compensating anions are fluoride anions F⁻, and methods for preparing said novel catalysts.
