In Co-catalyzed hydroformylation, where substantial phosphine rearrangement is required to stabilize the precatalyst and structures along the catalytic cycle, MOF-heterogenized phosphines reproduce homogeneous performance while offering recyclability and minimizing leaching (< 0.7 ppm Co).

We show via solid-state NMR studies that the phosphine ligands enjoy a high degree of mobility within the super-cages, which permits them to furnish mechanistically homogeneous and functionally heterogeneous transition-metal catalysts.

Our mechanistic proposal rationalizes why MOF-supported Rh(II) porphyrins are thermal hydrofunctionalization catalysts while molecular analogues prove unreactive. It also showcases the cooperation that can be achieved within a MOF matrix which precisely arranges Rh(II) centers in 3D space.

Via EPR and NMR spectroscopic analyses, kinetics, isotope labeling, IR spectroscopy, molecular model systems, radical trapping, digestion studies, quantum chemistry and molecular dynamics, we could get a rare level of insight into the mechanistic details of a heterogeneously catalyzed reaction.

3-Center-3-Electron σ-Adduct Enables Silyl Radical Transfer below the Minimum Barrier for Silyl Radical Formation
Transition-metal-catalyzed cleavage of the Si–H bond in silanes to yield silyl radicals requires substantial amounts of energy, which are commonly supplied by photons. For Rh(II) porphyrins, efficient...
Our mechanism study of a MOF-catalyzed hydrosilylation reaction is now available in #JACS.
Congratulations to all authors!

The graphic shows three regioisomers of diazines in the top row and shows a sketch of a pill with an attached arene. The latter alludes to the fact that the ability to prepare individual regioisomers permits researchers to optimize the position of nitrogen atoms in arene rings for applications in medicinal chemistry.
The bottom row shows simplistic representations of four different structomers of metal-organic frameworks. All four structomers have the same composition and are isostructural, but differ in how "active" and "inactive" metal sites are arranged within the structure. Selective preparation of individual structomers thus permits one to optimize metal arrangements in extended structures.
Our work on the development of structomers is now available as a preprint: chemrxiv.org/engage/chemr...
Congratulations to the authors Qiming Jin, Paolo Cleto Bruzzese, Alessandro Vetere, Claudia Weidenthaler, Eko Budiyanto, Mir Henglin, Nils Nöthling and Alexander Schnegg!
