Layered double alkoxides a novel group of layered double hydroxides without water content
BSTRACTIt has been generally accepted for long that water molecules are integral parts of layered double hydroxides (LDHs). It is even thought that in the absence of water molecules
there is no LDH structure. It is shown in this contribution that
via
the solvolysis of Mg- or Ca-alkoxides and Al-alkoxide with methanol or propanol and co-precipitated in methanolic methoxide
water-free LDH-like structures could be constructed. These novel LDH-like materials proved to be more active and selective catalysts in a Knoevenagel condensation than the corresponding ‘classical’ LDHs.
