Iron(II) complexes of ditopic carbanionic carbenes
Original language description
Reaction of dimesityliron(II) (Fe-2(mes)(4)) with the N-heterocyclic carbenes 1,3-bis(2,6-diisopropylphenyl)-imidazol-2-ylidene (IPr) and 1,3-bis(2,6-dimethylphenyl)hexahydropyrimidin-2-ylidene (6-Xyl) afforded the novel trigonal planar complexes [Fe(IPr)(mes)(2)] (1) and [Fe(6-Xyl)(mes)(2)] (2), respectively. Both species were structurally characterized by single crystal X-ray diffraction and display structures and magnetic responses consistent with a quintet ground state (S = 2). Reaction of 1 with KC8 in THF afforded K+ salts of the anionic complex [{:C[N(2,6-(Pr2C6H3)-Pr-i)](2)(CH)C}(2)Fe(mes)](-) (3) and the homoleptic organometallic anion [Fe(mes)(3)](-) (4). By contrast, reduction of 2 resulted in extensive decomposition and intractable productmixtures. Complex 3 is coordinated by two ditopic carbanionic carbenes via the C4/C5 position while the C2 position retains unquenched carbenic character and remains vacant for further coordination. This was corroborated by reacting solut
