Jones reagent formula

Rieche formylation Jones reagent is a solution prepared by dissolving chromium trioxide in aqueous sulfuric acid. To effect a Jones oxidation, this acidic mixture is then added to an acetone solution of the substrate. Alternatively, potassium dichromate can be used in place of chromium trioxide.

Oxalyl chloride The Jones Reagent is a solution of chromium trioxide in diluted sulfuric acid that can be used safely for oxidations of organic substrates in acetone. The reagent can also be prepared from sodium dichromate and potassium dichromate. Jones Reagent is especially suitable for the oxidation of secondary alcohols to ketones and of primary alcohols.

Chromic acid, also known as Jones reagent, is prepared by adding chromium trioxide (CrO 3) to aqueous sulfuric acid. There is a wide selection of oxidizing agents available for use in the organic chemistry laboratory, each with its own particular properties and uses.

Vilsmeier haack solvent Chromic acid, also known as Jones reagent, is prepared by adding chromium trioxide (CrO3) to aqueous sulfuric acid. The Jones oxidation also uses acetone as a co-solvent in the reaction to prevent over-oxidation of the organic product. A mechanism for the chromic acid oxidation of a ketone is shown below.

Gattermann formylation The Jones Reagent is a mixture of chromic trioxide or sodium dichromate in diluted sulfuric acid, which forms chromic acid in situ. The alcohol and chromic acid form a chromate ester that either reacts intramolecularly or intermolecularly in the presence of a base (water) to yield the corresponding carbonyl compound.

Pocl3 So if we react to our primary alcohol with sodium dichromate, sulfuric acid, and water, which we call the Jones reagent, in that mechanism we're going to oxidize our alpha carbon and lose one of those protons attached to the alpha carbon, which would give us an aldehyde functional group.
