Layered Double Hydroxides‐Supported Diisopropylamide: Synthesis, Characterization and Application in Organic Reactions

Abstract

Abstract 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‐NO 3 (as‐synthesized) and calcined LDH‐NO 3 . 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 27 Al MAS NMR spectroscopy, SEM and XPS (ESCA).
