Rhodium and iridium complexes of N-heterocyclic carbenes: Structural investigations and their catalytic properties in the borylation reaction

Synthesis and Characterization of N‐Heterocyclic Carbene Substituted Phosphine and Phosphite Rhodium Complexes and their Catalytic Properties in Hydrogenation Reactions

“…It is very efficient if mono-, di-or tetra-N-heterocyclic carbene-substituted rhodium(I) complexes are desired. [25,31,32] For the synthesis of mixed phosphine-or phosphite-substituted NHC rhodium complexes, the so-called "imidazolium route", [33] is not the most straightforward synthesis route.…”

Encapsulated N‐Heterocyclic Carbenes in Silicones without Reactivity Modification

“…In all cases, reaction proceeded smoothly with the conditions previously described, and the resulting products were obtained in high yields. In the same way, the synthesis of NHC-transition-metal complexes of Pd II , [22] Pt 0 , [23] and Rh II [24] were also successfully achieved with 1 a-PDMS or 1 c-MD 4 Ph M, indicating that the silicone polymer does not perturb the reaction. Moreover, PDMS appears to be suitable as the protecting media for the preparation of latetransition-metal complexes, since there are only very few reported cases where complexes are known to react with PDMS.…”

Synthesis of a Stable Disilyne Bisphosphine Adduct and Its Non‐Metal‐Mediated CO2 Reduction to CO

“…To quantify and characterize the released carbon monoxide (CO), the reaction was performed in the presence of a slight excess of {Rh I (cod)} (cod = cycloocta-l,5-diene) complex 6. A quantitative ligand-exchange reaction [14] was detected by 1 H NMR spectroscopy, leading to the corresponding Rh I carbonyl complex 7 (Scheme 4). [15] Alternatively, the obtained gas was diffused into another Schlenk tube connected by a metallic bridge and filled with a THF solution of 6.…”
