Descrição

Aplicação

Selenium dioxide (SeO₂) can be used as:

• An oxidizing agent to introduce carbonyl functional groups at activated carbon.
• A catalyst in the allylic hydroxylation reactions.
• An oxidant in the synthesis of amides by oxidative amidation of aldehydes with amines.
• A catalyst to synthesize di and trioxidized bicyclic cyclopentenones by reacting with Pauson-Khand reaction (PKR) products.
• A catalyst along with iodine (I₂) to prepare mono and bis-sulfenylindoles by treating indoles with diaryl disulfides via C-H sulfenylation.
• A catalyst to synthesize alkyl and aryl nitriles from the corresponding aldehydes via the formation of aldoxime.
• A selenium precursor to synthesize FeSe nanostructures via electrochemical deposition method.

It can also be used as a versatile reagent for allylic oxidation and oxidative-elimination reactions.
