The reactions require no metal catalyst and only Cs2CO3 as the base. A good functional group tolerance is achieved.Transition-Metal ComplexesCopper-Catalyzed ArylationChemoselective CarboxylationAlkenylboronic EstersAryl BromidesCo2PalladiumBondsHeteroarenesReagentsCarbon Dioxide as the C1 Source for Direct C−H Functionalization of Aromatic Heterocyclestext::journal::journal article::research article
