Abstract

In a simple one-pot reaction, mono-, di-, tri-, and polyalkylbenzenes, isomeric alkylhalobenzenea, and fluoro-,(trifluoromethy1)-, and 1, 3, 5-trifluorobenzene were converted to their corresponding diaryl sulfoxides with FSOaH. SbF5 (1: l)(magic acid)/SO* Dependency of the yields on the acidity (Ho) and the arene structure was demonstrated. Reduction of the formed sulfoxide was also observed as a minor pathway to give diaryl ...
