METHOD FOR PREPARING SOLID BASIC WADSWORTH-EMMONS REACTION CATALYSTS

摘要

The invention concerns a method for preparing a solid basic catalyst comprising a step which consists in heat treating a mixed magnesium hydroxide and a metal M of the rare earth family wherein the mol ratio Mg/M ranges between 1.5 and 5, said heat treatment consisting in bringing said mixed hydroxide to a temperature not less than 500 °C and not more than 1000 °C. The invention also concerns the use of the catalysts obtained by said method as heterogeneous catalysts for Wadsworth-Emmons reaction.
