Participants

Reaction Steps

A mixture of 4,4-bis-ethylsulfanyl-3-trifluoromethyl-1-(4-trifluoromethyl-phenyl)-but-3-en-1-one (example C.26 step 3) (36.96 g, 92 mmol) in TFA (54.3 mL) and water (5.8 mL) was refluxed for 18 h under nitrogen atmosphere, the exhaust of the reaction was passed through a NaOCl solution to trap the liberated ethyl mercaptane. The volatiles were evaporated and the mixture was diluted with water and extracted with TBME, the organic layer was washed with sat. NaHCO3-sol. and brine, dried over Na2SO4. Removal of the solvent in vacuum left the title compound as a brown oil (31.2 g, 95%), which was used without further purification [according to J. Fluorine Chem. 2001, 107, 281.]. MS (EI) 339.0 [(M−F)+].
