MODIFIED LAYERED DOUBLE HYDROXIDE (LDH) AND A PROCESS FOR PREPARATION THEREOF FOR C-C BOND FORMING REACTIONS

摘要

The present invention relates to a covalently organo-modified LDH (LDH/APTES) was found to be an efficient and reusable heterogeneous catalyst for C-C bond forming reactions (i.e. Aldol condensation, Knoevenagel condensation, Henry reaction, Michael addition). More particularly, this catalyst shows consistent activity for several cycles in C-C bond forming reaction. These catalysts were successfully characterized by XRD, FT-IR, ²⁹Si CP MAS NMR.
