A polymer-supported Pd(II) species has been prepared by means of an oxidative addition reaction between Pd(PPh 3) 4 and chloromethylated crosslinked polystyrene. This catalyst has been used for the hydrogenation of alkenes and alkynes under mild conditions. Quantitative studies on the rates of ...
Palladium-catalysed enantioselective diacetoxylation of terminal alkenes Article 15 February 2021 Data availability Data relating to the materials and methods, optimization studies, experimental procedures, DFT calculations, HPLC spectra, GC spectra and NMR spectra are available in the Supplementary Informa...
Electrocatalytic hydrogenation (ECH) produces high-value chemicals from unsaturated organics using water as a hydrogen source. However, ECH is limited by the low solubility of substrates when operated under aqueous conditions, by electrical losses when p
alkenesdensity functional calculationsThe catalytic homogeneous hydrogenation of electron-deficient alkenes (nucleophilic hydrogenation) was achieved in the presence of iridium complexes and a base as co-catalyst. Contrary to hydrogenation of electron-rich alkenes, which is inactivated by bases, the ...
