Selective Catalytic Hydrogenation of Arenols by a Well-Defined Complex of Ruthenium and Phosphorus–Nitrogen PN<sup>3</sup>–Pincer Ligand Containing a Phenanthroline Backbone
Selective catalytic hydrogenation of aromatic compounds is extremely challenging usingtransition-metalcatalysts. Hydrogenation of arenols to substituted tetrahydronaphthols or cyclohexanols has been reported only with heterogeneouscatalysts. Herein, we demonstrate the selectivehydrogenation of arenols to the corresponding tetrahydronaphthols or cyclohexanols catalyzed by a phenanthroline-based
