Abstract
Oxidation of alkyl silyl ethers of 5-hydroxymethyl-2-furfural to furane-2,5-dicarbaldehyde is promoted by N-bromosuccinimide in the presence of azoisobutyronitrile. The influence of solvent has been studied. Using 1,2-dichloromethane or dodecane as solvent, good yields are obtained from the trimethylsilyl or tert-butyldimethylsilyl derivatives.
