Efficient C(sp2)-H bond arylation has been achieved in water by using arene–ruthenium(II) catalysts containing nitrogen-based ligands. The substitution on the ligands proved to be an important tool to tune the activity of these catalysts. Mass spectrometrical analysis and
1H NMR spectroscopy were used for the identification of reactive intermediates and to gain more insights into the reaction pathway. More information can be found in the Full Paper by Sanjay
