L. Cottier et al., SYNTHESIS OF FURAN-2,5-DICARBALDEHYDE BY OXIDATION OF 5-SILYLOXYMETHYL-2-FURFURAL, Synthetic communications, 24(7), 1994, pp. 939-944
Oxidation of alkyl silyl ethers of 5-hydroxymethyl-2-furfural to furan
e-2,5-dicarbaldehyde is promoted by N-bromosuccinimide in the presence
of azoisobutyronitrile. The influence of solvent has been studied. Us
ing 1,2-dichloromethane or dodecane as solvent, good yields are obtain
ed from the trimethylsilyl or tert-butyldimethylsilyl derivatives.
