资源简介：
Iron(II) and iron(III) complexes containing the 1,3-dimesitylimidazole-2-ylidene
(IMes) and 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IPr)
ligands have been prepared and characterized. Four-coordinate iron(II)
carbene species are sensitive to the steric bulk of the carbene ligand
and can adopt both monomeric and halide-bridged dimeric structures
with 2:1 and 1:1 carbene to iron stoichiometries, respectively. Iron(III)
carbene complexes bind a single carbene ligand, which is easily exchanged
in solution. The structural and solution phase characterization of
all compounds is reported, and their relevance to iron-catalyzed C–C
coupling reactions is discussed.
