N,N′-dibromo-N,N′-1,2-ethanediylbis(benzenesulphonamide) (BNBBS): A safe, neutral and efficient reagent for the oxidation of primary and secondary alcohols to corresponding carbonyl compounds under mild conditions

Efficient oxidation of various types of structurally diverse alcohols to the corresponding carbonyl compounds can be carried out with N,N′-dibromo-N,N′-1,2-ethanediylbis(benzenesulphonamide) in good to high yield of products in CH2Cl2 at room temperature. Primary (aliphatic, benzylic and allylic) alcohols are oxidized with no over-oxidation to carboxylic acids.

Oxidation of Primary and Secondary Alcohols by the Catalysis of Palladium

Saturated and unsaturated alcohols are oxidized to the corresponding ketones in good or excellent yields by using an aryl halide (phenyl bromide or mesityl bromide) as an oxidant and palladium(0) or -(II) as a catalyst (0.6-3 mol percent relative to the alcohol) in the presence of a base (NaH or K2CO3).The similar oxidation of primary alcohols provides the corresponding aldehydes and/or esters.The aldehyde/ester selectivity is correlated to the steric and electronic features of substrates.The procedure is applied to the oxidation of 1-primary,ω-primary diols to lactones.
