Chapter 7 NHC-Iron, Ruthenium and Osmium Complexes in Catalysis

[en] In this Chapter, the catalytic applications of organometallic species -either pre-formed or generated in situ- based on Group 8 transition metals and N-heterocyclic carbene (NHC) ligands are surveyed. Thus far, only a few reports on the use of NHC-Fe complexes in organic catalysis are available, although significant work has been reported in the related field of biocatalysis. Contrastingly, the chemistry of NHC-Ru complexes has reached an unprecedented level of maturity, thanks to the relentless research efforts thrown into the development of olefin metathesis catalysts. Other carbon skeletal transformations based on NHC-Ru promoters include cyclopropanation, allylation, or cycloisomerisation reactions. Lastly, with only two reports to date concerning olefin metathesis and transfer hydrogenation, NHC-Os-based catalysis can hardly be considered anything else than a curiosity.
