Application
与氯化铵一起用于将氢化苯偶姻氧化成苯偶酰。
Chromium (VI) oxide may be employed as a catalyst for the following reactions:
- Transformation of various primary alcohols to carboxylic acids.
- Oxidation of arenes (naphthalenes and anthrathene) to the corresponding quinones by using periodic acid as the terminal oxidant in acetonitrile.
- Benzylic oxidation of various substituted toluene to the corresponding benzoic acids.
- Oxidation of sulfides to sulfones.
General description
Chromium (VI) oxide is acidic anhydride of chromic acid. It is a useful oxidizing reagent for the conversions of:,Carbon-hydrogen bonds to alcohols,,Alkenes to α, β-unsaturated ketones,Alcohol to aldehydes, acids, and keto acids.

NAD(P)H:quinone oxidoreductase (Nqo1)-mediated detoxification of quinones plays a critical role in cancer prevention. Metals alter the carcinogenicity of AhR ligands, such as TCDD, by modulating the induction of Nqo1, but the mechanism(s) remain unresolved. To decipher the molecular mechanisms involved
