一般說明

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.

應用

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.
