Z‐Retentive Enantioselective Rh‐Catalyzed Hydroarylation of E,Z‐Dienes
Angewandte Chemie, EarlyView.The Rh‐catalyzed hydroarylation of conjugated E,Z‐dienoates is found to proceed with high selectivity for addition to the E‐alkene unit. Mechanistic analysis of this Z‐retentive process points towards preferred binding of the E‐alkene unit to a Rh‐aryl species to give rise to the observed selectivity and that Rh‐enolate protonolysis to be turnover ...

DFT Investigation into the Role of Conventional and Ionic Liquids as Solvents in Olefin Metathesis
International Journal of Electrochemical Science, 2013 The effects of conventional and ionic liquids on the metathesis of olefin have been investigated by means of quantum chemical calculations to establish the factors favouring the metathesis of olefin in ionic liquid. The results suggest that ionic liquids

Ruthenium-based olefin metathesis catalysts with monodentate unsymmetrical NHC ligands
Beilstein Journal of Organic Chemistry, 2018 An overview on the catalytic properties of ruthenium complexes for olefin metathesis bearing monodentate unsymmetrical N-heterocyclic diaminocarbene ligands is provided. The non-symmetric nature of these NHC architectures strongly influences activity and

Probing the Electronic Structure of Spectator Oxo Ligands by 17O NMR Spectroscopy
CHIMIA, 2020 Spectator oxo ligands are ubiquitous in catalysis, in particular in olefin epoxidation and olefin metathesis. Here we use computationally derived 17O NMR parameters to probe the electronic structure of spectator oxo ligands in these two reactions.
