Sažetak
Ruthenium(II)-catalysed C-H bond activation of arenes containing a functional directing group depends on the ligand coordinated to ruthenium(II). In this study, 2-phenylpyridine C-H activation catalysed by a “piano-stool” ruthenium(II) complex containing a fluorinated β-diketonate ligand was examined by ESI-MS in combination with CID experiments. [Ru(β- diketonate)(CTPhPy)Cl]^+ was identified as an active intermediate, and its collisional activation leads to C-H activation. CID analysis indicates proton transfer from the phenylpyridine to the chlorine anion, showing HCl elimination, while the β-diketonate ligand is retained in the complex together with the activated phenylpyridine. Furthermore, DFT calculations were performed for the neutral analogue [Ru(β-diketonate)(PhPy)Cl] to identify all ruthenium intermediates along the C-H activation reaction pathway. The results suggest that the most stable structure of [Ru(β-diketonate)(PhPy)Cl] has pre-activated 2- phenylpyridine with a partly developed Ru-H bond. Further, we show that K_2CO_3 is not directly involved in the C-H activation step and it serves in the reaction as a base.
