BaMoO4 is useful as a framework for doped photoluminescent materials, but its synthesis typically involves high temperature methods.  MoS2 is a layered structure, and could serve as a source of molybdenum, but it is unreactive under standard conditions.  MoS2 may be exfoliated by first intercalating lithium into the crystal structure using butyl lithium, and then exposing this compound to water.  This aqueous colloidal form of MoS2 is highly reactive, and upon exposure to Ba2+, it undergoes an oxidative reaction to form BaMoO4.  In this reaction, water serves as the oxidant and the oxygen source, and the sulfide is likely released as H2S/BaS.  The effects of reaction conditions, including the solvent, temperature, ion composition, and concentration are discussed.
