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.
据报道,在130°C下,使用无配体的Pd(OAc)2作为催化剂,以KOAc为碱,有效地从不同取代的2-溴-二芳基亚磺酰基基团中获得了二苯并噻吩-S-氧化物。以优异的产率获得了各种二苯并噻吩-S-氧化物。
