Regarding the tailoring of the macroligand, the incorporation of diphosphines drastically increases the catalytic activity and stability of the immobilized Ru species. Spatially close diphosphine ligands seem to allow bidentate coordination, referring to the superior effect of polyphosphines with the building units bis(diphenylphosphino)methane, Xantphos or BINAP. However, P-dppm-Ru suffers from an insufficient stability and a continuous deactivation, whereas P-Xantphos-Ru and P-BINAP-Ru reach steady state activities after a certain induction period. The respective initial degradation can be mainly attributed to oxidation processes of the phosphine centers and the formation of carbonyl ligands that bind to the Ru species and modify the catalytically active complex.
