Abstract:
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.
