Article abstract of DOI:10.1055/s-1985-31445

A new synthesis of 2-trifluoromethyl-1,4-benzoquinone and 2-chloro-2-trifluoromethyl-1,3-cyclopentanedione by oxidation of 3-trifluoromethylphenol with sodium chlorite/sulfuric acid (chlorous acid) is described.In addition, the hydrodechlorination of 2-chloro-2-trifluoromethyl-1,3-cyclopentanedione to give 2-trifluoromethyl-1,3-cyclopentanedione by hydroiodic acid (generated in catalytic amounts from iodine and thiophenol) has been achieved.
