Li, Wei published the artcileDesign of Ru(II)-NHC-Diamine Precatalysts Directed by Ligand Cooperation: Applications and Mechanistic Investigations for Asymmetric Hydrogenation, Name: 3-Acetylthiophene, the main research area is ruthenium heterocyclic carbene complex diamine precatalyst preparation; isocoumarin benzothiophene dioxide ketone enantioselective hydrogenation.
A modular synthesis of Ru(II)-NHC-diamine complexes from readily available chiral N-heterocyclic carbenes (NHCs) and chiral diamines is disclosed for the first time. The well-defined Ru(II)-NHC-diamine complexes show unique structure and coordination chem. including an unusual tridentate coordination effect of 1,2-diphenylethylenediamine. The isolated air-and moisture-stable Ru(II)-NHC-diamine complexes act as versatile precatalysts for the asym. hydrogenation of isocoumarins, benzothiophene 1,1-dioxides, and ketones. Moreover, based on the identification of reaction intermediates by stoichiometric reactions and NMR experiments, together with the DFT calculations, a possible catalytic cycle was proposed.
