Popis

General description

Molybdenum(VI) dichloride dioxide is an oxo-halide of molybdenum widely used as a catalyst for various organic transformations. It is an oxo-transfer catalyst that has the ability to promote oxidation as well as reduction reactions. It can also be used as a chemical vapor deposition(CVD) precursor to synthesize various Mo-based nanomaterials.

Application

Molybdenum(VI) dichloride dioxide can be used as a catalyst:

• For thioacetalization of heterocyclic, aromatic, and aliphatic compounds.
• To synthesize mono-, di-, tri-, and tetracarbamates from alcohols and aromatic or aliphatic isocyanates.
• For stereospecific deoxygenation of epoxides to alkenes.
• For the synthesis of dihydropyrimidinone/thione and polyhydroquinoline derivatives via a Biginelli and Hantzsch reaction.

It can also be used as a precursor to synthesize MoO₂ nanoparticles.
