title: Palladium-catalyzed intramolecular direct arylation of 2-bromo-diaryl sulfoxides via C-H bond activation.
abstract: Efficient access to dibenzothiophene-S-oxides from differently substituted 2-bromo-diarylsulfinyl moieties using ligandless Pd(OAc)2 as the catalyst and KOAc as the base in dimethylacetamide at 130 °C is reported. Various dibenzothiophene-S-oxides were obtained in excellent yields.
