Use of a new modified solid basic catalyst comprising a hydrotalcite structure which includes compensating fluoride ions for Knoevenagel and Michael condensation reactions

摘要

Improved yields in the Knoevenagel and Michael condensation reactions are obtained by using heterogeneous solid catalyst based on a carbonated and hydrated magnesium/aluminum hydroxide. The use of a solid basic catalyst comprising a hydrotalcite structure is claimed in which part of the compensating anions in the core of the structure are fluoride ions. The catalyst is used in Knoevenagel and Michael condensation reactions. Independent claims are also included for the catalyst itself and its preparation.
