Palladium-catalyzed double C-H activation directed by sulfoxides in the synthesis of dibenzothiophenes
Samanta, Rajarshi,Antonchick, Andrey P.
, p. 5217 - 5220 (2011)
S=O shows where to go: A novel double C-H activation of aromatic compounds with a sulfoxide as a directing group results in the highly regioselective synthesis of polysubstituted dibenzothiophenes (see scheme). The reaction cascade consists of palladium-catalyzed double C-H activation and a Pummerer rearrangement followed by palladium-catalyzed C-S bond formation. Copyright
