Palladium-Catalyzed Direct C7-Arylation of Substituted Indazoles
, 2016 A novel direct C7-arylation of indazoles with iodoaryls is described using Pd(OAc)2 as catalyst, 1,10-phenanthroline as ligand, and K2CO3 as base in refluxing DMA. Direct C7-arylation of 3-substituted 1H-indazole containing an EWG on the arene ring gave

Palladium-Catalyzed intramolecular direct arylation of aromatic tertiary amide compounds revisited
Results in Chemistry, 2022 We have investigated the palladium-catalyzed intramolecular direct arylation of three aromatic tertiary amide compounds. For the C–H activation of the benzene ring, heating over 120 °C in the presence of PCy3·HBF4 and PivOH was indispensable, and the ...

Palladium-Catalyzed Direct Arylation of Selenophene [PDF]
Proceedings of the 15th Brazilian Meeting on Organic Synthesis Proceedings, 2013 An efficient and convenient method was developed for the regioselective formation of 2-aryl- or 2,5-diarylselenophenes via a palladium-catalyzed direct arylation. This protocol is suitable for a wide range of aryl halides containing different functional groups.

Ruthenium-catalyzed direct arylations with aryl chlorides
RSC Advances, 2016 Aryl chlorides are readily available at lower cost than the corresponding bromides and iodides, but are much more challenging as substrates in metal-catalyzed cross-couplings.

Aryl Bromides and Aryl Chlorides for the Direct Arylation of Benzylic Amines Mediated by Ruthenium(II) [PDF]
European Journal of Organic Chemistry, 2013 AbstractThe ruthenium(II)‐catalyzed sp3 C–H bond arylation of benzylic amines with aryl halides is reported. In the present method, aryl iodides and, more importantly, also the cheaper aryl bromides and aryl chlorides can be applied as aryl sources. Additionally, the method does not require elaborate manipulations in a glove box and can be carried out ...
