Introduction to Oxidation
The carbon atom of a carbonyl group has a comparatively high oxidation state. In the fact this is reflected that most of the reactions explained so far either cause no change in the oxidation state (example acetal and imine formation) or influence a reduction (for example organometallic additions and deoxygenations). The most general and characteristic oxidation reaction is the conversion of aldehydes to carboxylic acids. In the shorthand equation displayed here the [O] symbol considers to not specified oxidation conditions which influce the desired change. Various distinct techniques of accomplishing this transformation will be explained here.
RCH=O + [O] RC(OH)=O
We noticed that Jones' reagent (aqueous chromic acid) converts aldehydes to carboxylic acids, most probably through the hydrate, in discussing the oxidations of 1º and 2º-alcohols. Another reagents, among them aqueous potassium permanganate and dilute bromine, result similar transformation. Even oxygen in air will slowly oxidize aldehydes to peracids or acids, most expected by a radical technique. Helpful tests for aldehydes, Tollens' test, Benedict's test & Fehling's test, take benefit of this easiness of oxidation by using Ag(+) and Cu(2+) as oxidizing agents (oxidants).
RCH=O + 2 [Ag(+) OH(-)] RC(OH)=O + 2 Ag (metallic mirror) + H2O
Like in the above equation, When silver cation is the oxidant, it is reduced to metallic silver in the course of the reaction and this deposits like a beautiful mirror on the inner surface of the reaction vessel. The Benedict and Fehling tests make use of cupric cation like the oxidant. This deep blue reagent is reduced to cuprous oxide, that precipitates as a red to yellow solid. All these cation oxidations might be conducted within the alkaline conditions. To prevent precipitation of the insoluble metal hydroxides, the cations might be stabilized as complexed ions. Cupric ions are employed as citrate or tartrate complexes and silver is employed as its ammonia complex, Ag(NH3)2(+).
Saturated ketones are normally inert to oxidation conditions that convert aldehydes to carboxylic acids. yet, under vigorous acid-catalyzed oxidations with nitric or chromic acids ketones may go through carbon-carbon bond cleavage at the carbonyl group.
