<i>trans</i>-Selective and Switchable Arene Hydrogenation of Phenol Derivatives
A trans-selective arene hydrogenation of abundant phenolderivatives catalyzed by a commercially available heterogeneous palladium catalyst is reported. The described method tolerates a variety of functional groups and provides access to a broad scope of trans-configurated cyclohexanols as potential building blocks for life sciences and beyond in a one-step procedure. The transformation is strategically
