产品说明

应用

Manganese(IV) oxide (MnO₂) can be used as an oxidizing agent for the oxidation of:

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.
