Layered double hydroxides (LDHs) are inorganic anion exchangers with basic surface properties. Combination of these LDHs with d0 oxy-anions leads to a class of oxidatively stable and leak-free heterogeneous oxidation catalysts. Using peroxides as the oxidant, WO4
2--LDH and V10O28
6--LDH catalyze epoxidations; WO4
2--LDH effects bromide oxidation and bromide-assisted epoxidation; MoO4
2--LDH is an inorganic generator of 1O2 from H2O2. The properties of these LDH catalysts can be finely adjusted in order to perform synthetically useful reactions.
