This report describes a carboxylate-assisted palladium-catalysed Catellani reaction, which is compatible withortho-amination and unactivated C(sp2)-H arylation. This method was used to synthesize a series of 1-amino substituted dihydrophenanthridines, phenanthridines and 6H-benzo[c]chromenes. Based on kinetic isotope experiments, the kinetic curve proves that pivalic acid accelerates the reaction rate of unactivated C(sp2)-H activation, and thus this rate can keep up with the five membered aryl-norbornene-palladacycle (ANP) intermediate.

An efficient approach to the synthesis of benzimidazole derivatives has been achieved by copper-catalyzed double C-N bonds formation of N-alkyl-2-iodoaniline and sodium azide. The reaction was supposed to proceed through copper-catalyzed tandem reaction of SNAr reaction, aerobic oxidation of C(sp3)-H bond and intramolecular C-N bond formation sequence. Structurally diverse 2-aryl, alkenyl and alkyl benzoimidazole derivatives were assembled by this methodology.

A method for convenient synthesis of N-alkyl-2-aryl-indole-3-carbaldehyde has been described. A variety of highly valuable indolyl aldehydes have been prepared through this method. Electron donating groups on both aromatic rings (anilinyl and benzyl) facilitate the formation of the desired products. A benzylic C-H insertion by rhodium carbene is the key step for this transformation. This journal is
