Jones reagent is an acidic solution of chromium trioxide (CrO3) in acetone, used to oxidize primary alcohols to carboxylic acids and secondary alcohols to ketones. This powerful oxidizing agent is known for its rapid, exothermic reactions and its ability to tolerate other functional groups, such as unsaturated bonds, which are rarely affected by the reagent.
Key Uses Jones Reagent CAS 65272-70-0 :
- Oxidation Reactions:Converts primary alcohols to carboxylic acids (e.g., -CH₂OH to -COOH) and secondary alcohols to ketones (e.g., -CH(OH)- to >C=O).
- Chemical Synthesis:Acts as a key intermediate for creating complex organic molecules, including acyl-naphthols and specific isocoumarins.
- UV-Curing Materials:Used in industrial applications for rapid curing of coatings, inks, and adhesives, notes NINGBO INNO PHARMCHEM CO.,LTD..
- Oxidative Cleavage:Can cleave alkenes to form carboxylic acids and ketones.
Key Applications:
- Jones Oxidation:The primary use is in the Jones oxidation of alcohols, converting:
- Primary alcohols to carboxylic acids.
- Secondary alcohols to ketones.
- Oxidative Cleavage:Can be used for the oxidative cleavage of alkenes to form carboxylic acids or ketones.
- Synthesis of Complex Molecules:Employed in preparing specific organic compounds, such as symmetrical binaphthols or substituted isocoumarins.
