Synthesis and Characterisation of a Heterobimetallic N-heterocyclic Carbene Rhodium Ruthenium Complex as Catalyst for Transfer Hydrogenation

Heterobimetallic Complexes of Bi- or Polydentate N-Heterocyclic Carbene Ligands and Their Catalytic Properties

“…Kühn and co-workers metalated 91 with the use of Ag 2 O and then [RhCl(cod) 2 ] to afford the Ru/Rh heterobimetallic NHDC complex 97 (Scheme 30) (solid-state structure determined by X-ray diffraction) with the intermediate formation of the Ag-linked dimer 92 [51]. The catalytic efficiency of 97 was tested in the transfer hydrogenation of acetophenone with basic 2-propanol as a H-donor (0.1 mol% catalyst, 2 mol% NaO í Pr, 80 • C).…”

“…28 Considering the wide variety of ruthenium(II) complexes, this paper only focuses on one class, the Ru-NHC complexes. Ru-NHC complexes have broad catalytic potential in a wide range of synthetic applications, including transfer hydrogenation of ketones, 29,30 metathesis reactions, 31 secondary oxidation of alcohols, 32 N-alkylation of amines, amides oxidation, and sulfonamides 33,34 and Oppenauer-type oxidations. 35,36 In previous studies, we introduced various substituents into ruthenium complexes, and synthesized four ruthenium complexes with MIC values ranging from 0.003 to 0.050 mg mL À1 against Staphylococcus aureus.…”
