Overview

Jones reagent is a solution of chromium trioxide in aqueous sulfuric acid.Using acetone as a reaction solvent, the reagent is usually used for the oxidation of primary and secondary alcohols to carboxylic acids and ketones, respectively.The oxidation is very rapid and exothermic.The reagent tolerates a variety of functionalities, such as, for example, unsaturated bonds, which are rarely oxidized.For a comprehensive review of chromium-based reagents, see "Oxidation of Alcohols to Aldehydes and Ketones" by Tojo and Fernández, Springer Berlin, 2006, 1-97.Jones reagent can be used:In the oxidative cleavage of various alkenes into carboxylic acids and ketones using a catalytic amount of osmium tetroxide.To prepare symmetrical binaphthols by oxidative dehydrodimerization of substituted naphthols.To synthesize acyl-naphthols and substituted isocoumarins from 2-(4-hydroxy-but-1-ynyl)benzaldehydes.
