Oxidation of 3-furfurylcarbinols 3a-e and 7 with bromine in acetone-water solution gave the 2-substituted-3-furfurals 4a-e and 8 in good yields, respectively. Reaction of 2-alkyl-3-furfurylcarbinols 9a and 9b with bromine in acetone-water gave the bromoalkyl 3-furfuryl ketones 10a and 10b as the major products. A reaction mechanism via the cis-trans isomerization of the 2-ene-1,4-diones 13 and 14 was
