Oxidative conversion of aldoximes into carboxylic acid esters

Said,Skarzewski,Mlochowski

, p. 1851 - 1862 (2007/10/02)

Aromatic and aliphatic aldoximes or their O-methyl ethers can be efficiently converted into the corresponding carboxylic acid esters by treatment with an alcoholic solution of 30% hydrogen peroxide in the presence of catalytic amounts of 2-nitrobenzeneseleninic acid. Primary alcohols give excellent to good yields, secondary ones - good to moderate, but with tertiary alcohols no esterification is observed.
