Application
- Allylic alcohols to α, β-ethylenic aldehydes, or ketones.
- Propargylic alcohols to alkynic aldehydes or ketones.
- Benzylic and heterocyclic alcohols to conjugated aromatic aldehydes or ketones.
- Amines to aldehydes, imines, amides, and diazo compounds. Methyl arenes to form primary amides in the presence of urea and oxygen.
- MnO2 can also be used to synthesize disubstituted oxazolines from aldoximes via in situ nitrile oxide formation. Non-activated cyclic and acyclic alcohols oxidized to ketone analogs using stoichiometric MnO2 and a ruthenium catalyst.
