  author={Petra Kuzman and Franc Po{\vz}gan and Anton Meden and Jurij Svete and Bogdan {\vS}tefane},
The synthesis of a range of new cyclometallated organoruthenium(II) complexes through the ortho‐C−H activation of the aryl group in 2‐aryl‐substituted quinazolines with [RuX2(p‐cymene)]2 is described. The beneficial effect of the carboxylate ligand on both the cyclometallation and the further arylation reaction step was demonstrated. Mechanistic studies reveal that bromide and iodide anions decelerate the arylation process by an in situ ligand exchange reaction. Additionally, a detailed NMR…

Ru-Catalysed C–H Arylation of Indoles and Pyrroles with Boronic Acids: Scope and Mechanistic Studies
The Ru-catalysed C2–H arylation of indoles and pyrroles by using boronic acids under oxidative conditions is reported and Mechanistic studies suggest the on-cycle intermediates do not possess a para-cymene ligand and that theOn-cycle metalation occurs through an electrophilic attack by the Ru centre.
