Intercalation of (Mo(VI)O2(O2CC(S)Ph2)2)2- in a Zn(II)-Al(III) layered double hydroxide host: a strategy for the heterogeneous catalysis of the air oxidation of thiols

The intercalation into layered double hydroxide layers prevents the formation of monomeric and dimeric Mo(V) species. The system has the advantage of using water as a solvent instead of aprotic solvents. Addition of water to PhSH ethanolic solutions increases the oxidation reaction rate and offers a method of contaminant thiol elimination.
