Efficient synthesis of π-conjugated molecules incorporating fluorinated phenylene units through palladium-catalyzed iterative C(sp(2))-H bond arylations

Halo-substituted benzenesulfonyls and benzenesulfinates: convenient sources of arenes in metal-catalyzed C–C bond formation reactions for the straightforward access to halo-substituted arenes

The use of halo-substituted ArSO₂R as an aryl source in metal-catalyzed C–C bond formation reactions presents several advantages, as the reaction often proceeds without cleavage of the C–halo bonds.

Pd-Catalyzed regioselective intramolecular dehydrogenative C-5 cross coupling in anN-substituted pyrrole-azole system

A C5-selective intramolecular dehydrogenative cross coupling inN-substituted pyrrole-azoles in the presence of a reactive C2 position is achieved.

Palladium-catalyzed direct desulfitative C2 arylations of 3-halo-N-protected indoles using (hetero)arenesulfonyl chlorides

Halo-substituents at the indolyl C3 position act as temporary blocking groups allowing the regioselective formation of 2-arylindoles through a direct desulfitative arylation. This method allows one to prepare a wide variety of indole derivatives in a few steps.
