- ... Nuclear magnetic resonance (NMR) and total neutron scattering techniques are established methods for the characterisation of liquid phases in confined pore spaces during chemical reactions. Herein, we describe the first combined total neutron scattering – NMR setup as a probe for the catalytic heterogeneous reduction of benzene-d₆ with D₂ in 3 wt% Pt/MCM-41. ...

- ... The asymmetric nucleophilic catalysis by fluoride ions at a carbon-based electrophile has been demonstrated for the first time. Using a library of ad hoc designed bifunctional phase-transfer catalysts in which both the anion and the cation are directly involved in the reaction, the desymmetrisation of meso-succinic and -glutaric anhydrides is possible. ¹⁹F NMR spectroscopic studies support the int ...
