Reactions of organic compounds in aqueous hydrofluoric acid

Anthraquinone with HNO3 or N2O4 in 80-98% HF gave nitroanthraquinone. The presence of H2O enabled the reaction temp. of 30-40 Deg to be maintained without external pressure and made the sepn. of the 2 isomers easier. Me(CH2)7SH with NO2 and HF gave Me(CH2)7SO2F. The yield varied with the concn. of HF; no product was obtained with an HF concn. of <40%. [on SciFinder (R)]
