Especially, soft and strongly ligating phosphines are the donor atoms of choice. The early work by Reppe established triphenylphosphine as prototypical phosphine and initiated the exploration of the ligand sphere, crafting the microenvironment of the metal center. A remarkable example of this design process is Xantphos, a bidentate phosphine ligand with a rigid backbone and a wide bite angle, which has been addressed by recent reviews. While Xantphos was originally applied for hydroformylation catalysis , its superior properties as ligand also occur in hydrocyanation , cross-coupling reactions and C-H activation reactions forming C-C and C-X bonds . Due to its versatility, Xantphos derivatives have been subject to various approaches of immobilization, which aim to transfer the molecular moiety into an easily separable catalyst. These attempts include encapsulation , anchoring on a silica surface or polymer matrix , immobilization on a supported ionic liquid phase or the radical polymerization of vinyl functionalized Xantphos species. However, all of the approaches require several complex preparation steps, increasing the expense for the immobilization. In our work, we developed a simple and scalable design strategy for a heterogenized, Xantphos-based ruthenium catalyst. Based on the concept of hyper-crosslinked polymers (HCPs) , we incorporated Xantphos in a porous organic polymer and investigated the ruthenium impregnated catalyst in the direct hydrogenation of CO2 to formic acid (FA). Herein, we present the synthesis and characterization of the novel catalyst and highlight its catalytic behavior, focusing on the stability and its alterations over the catalytic process.
