Sodium Hypochlorite Oxidation of Secondary Alcohols

We now report that secondary alcohols are cleanly oxidized to ketones with sodium hypochlorite in acetic acid in the absence of catalyst Inexpensive concentrated solutions of sodium hypochlorite are sold commercially as swimming pool chlorine 6 Dropwise addition of this reagent to a solution of the alcohol in acetic acid at room temperature leads to an exothermic reaction which is usually

Asymmetric Reduction and Oxidation of Aromatic Ketones

An enantioselective asymmetric reduction of phenyl ring-containing prochiral ketones to yield the corresponding optically active secondary alcohols was achieved with W110A secondary alcohol dehydrogenase from Thermoanaerobacter ethanolicus (W110A TESADH) in Tris buffer using 2-propanol (30% v/v) as cosolvent and cosubstrate This concentration of 2-propanol was crucial not

Oxidation of alcohols is one of the most fundamental reactions in organic chemistry A great variety of metal and non-metal-based stoichiometric reagents have been developed to oxidize primary and secondary alcohols to the corresponding aldehydes ketones and carboxylic acids 1 2 3 These processes generally produce significant amount of inorganic or organic wastes that are of

Where a secondary alcohol is oxidised it is converted to a ketone The hydrogen from the hydroxyl group is lost along with the hydrogen bonded to the second carbon The remaining oxygen then forms double bonds with the carbon This leaves a ketone as R 1 –COR 2 Ketones cannot normally be oxidised any further because this would involve breaking a C–C bond which requires too much energy

Synthesis of Ketones

The oxidation of secondary alcohols to ketones may be carried out using strong oxidizing agents because further oxidation of a ketone occurs with great difficulty Normal oxidizing agents include potassium dichromate (K 2 Cr 2 O 7) and chromic acid (H 2 CrO 4) The conversion of 2‐propanol to 2‐propanone illustrates the oxidation of a

Aldehydes and Ketones

Aldehydes can be formed by oxidizing a primary alcohol oxidation of a secondary alcohol gives a ketone What happens when we try to oxidize a tertiary alcohol? The answer is simple: Nothing happens There aren't any hydrogen atoms that can be removed from the carbon atom carrying the OH group in a 3 alcohol
