Article abstract of DOI:10.1039/c39950002319

The treatment of p-(phenylsulfinyl)phenyl ethers 1 with trifluoroacetic anhydride in the presence of styrene selectively caused the direct ipso-substitution of the sulfinyl groups by trifluoroacetoxy groups, giving the protected dihydroquinone derivatives 3 in high to quantitative yields.
