Amidato complexes of ruthenium, rhodium and iridium from concise N–H bond activation: exploration in catalysis
摘要:
Acceptor-substituted N-H groups as found in carbamides and sulfonamides are readily activated through suitable unsaturated metal complexes applying the concept of metal-ligand bifunctionality. This process constitutes the basis for an enantioselective intramolecular addition of N-H groups onto activated alkenes. The resulting compounds can also be employed as catalyst precursors for transferhydrogenation. (C) 2015 Published by Elsevier Ltd.

The concept of metalâligand bifunctionality can be employed for an efficient activation of NâH bonds by well-defined ruthenium amido complexes. An enantioselective catalytic aza-Michael reaction was developed on the basis of this process, which gives rise to indoline β-amino acids.
