Understanding the leaching properties of heterogenized catalysts: a combined solid-state and PHIP NMR study.
Torsten Gutmann,Tomasz Ratajczyk,Yeping Xu,Hergen Breitzke,Anna Grünberg,Sonja Dillenberger,Ute Bommerich,Thomas Trantzschel,Johannes Bernarding,Gerd Buntkowsky +9 more
TL;DR: PHIP NMR in solution, combined with solid-state MAS-NMR study reveals that there are two different species of catalysts on the silica, namely coordinatively bound catalysts and physisorbed catalyst.

Solid‐State NMR Characterization of Wilkinson’s Catalyst Immobilized in Mesoporous SBA‐3 Silica
TL;DR: It is concluded that two triphenylphosphine ligands are replaced and that the catalyst is bonded to the silica surface through two linker molecules.

- 12 Jul 2012
TL;DR: Solid state NMR techniques have become a major tool for the characterization of immobilized homogeneous catalysts, tethered to a solid support material as discussed by the authors, which can work with typical ill-defined real-world systems.

Immobilization and Characterization of RuCl2(PPh3)3 Mesoporous Silica SBA-3
TL;DR: In this paper, the five-fold coordinated ruthenium (II) catalyst RuCl2(PPh3)(3) is heterogenized on the surface of amine functionalized mesoporous silica material SBA-3 and studied by BET, XRD and P-31 CP-MAS solid-state NMR.
New investigations of technical rhodium and iridium catalysts in homogeneous phase employing para-hydrogen induced polarization.
Torsten Gutmann,Tomasz Ratajczyk,Sonja Dillenberger,Yeping Xu,Anna Grünberg,Hergen Breitzke,Ute Bommerich,Thomas Trantzschel,Johannes Bernarding,Gerd Buntkowsky +9 more
TL;DR: It is shown that the para-hydrogen induced polarization (PHIP) phenomenon in homogenous solution containing the substrate styrene is also observable employing simple inorganic systems of the form MCl(3)·xH(2)O (M=Rh, Ir) as catalyst, confirming that already very simple metal complexes enable the creation of PHIP signal enhancement in solution.
