The layered double hydroxides-supported diisopropylamide (LDH-DA) catalyst is found to be an efficient and selective solid base for aldol, Knoevenagel, Henry, Michael, transesterification and epoxidation reactions under liquid phase conditions. LDH-DA is synthesized by the interaction of lithium diisopropylamide with LDH-NO3 (as-synthesized) and calcined LDH-NO3. The LDH-DA (Mg/Al, 3/1) and their precursors are well characterized by using various instrumental techniques such as FT-IR, TGA and DTA, powder XRD, solid state 27Al MAS NMR spectroscopy, SEM and XPS (ESCA).

experimental part, p. 5267 - 5274 (2009/05/26)
Chiral bisphosphazides complexed with lithium salts efficiently catalyze the direct enantioselective 1,4-addition of dialkyl malonates to acyclic enones. Spectroscopic studies on the stoichiometry of the bisphosphazide and lithium salt have indicated the
Magnesium-lanthanum mixed metal oxide: A strong solid base for the michael addition reaction

Michael additions were achieved quantitatively at room temperature with a broad spectrum of acceptors and donors, using a magnesium-lanthanum mixed oxide, a strong solid base. The best solvent for the reaction is dimethylformamide, but good yields were al
