چکیده
The potassium salt of an extremely bulky β-diketiminate, [K(Ar*Nacnac)] (Ar*Nacnac, [(Ar*NCMe)2CH]−; Ar*, C6H2Me{C(H)Ph2}2-4,2,6) was reacted with either CaI2 or YbI2(THF)2, which afforded [(Ar*Nacnac)MI] (M = Ca Yb). These are the first examples structurally characterised, donor solvent-free, N-arene substituted β-diketiminato calcium and ytterbium complexes that incorporate a terminal iodide ligand. Reduction [(Ar*Nacnac)CaI] sodium metal gave complex product mixture, from few crystals β-diketiminate C–H activated product, [{Ca(μ-Ar*Nacnac-H)}2], were obtained crystallographically characterised. In attempt to form hydride compound, treatment [(Ar*Nacnac)YbI] K[HBEt3] good yield contact ion pair compound [(Ar*Nacnac)Yb(HBEt3)].

Chemistry of nitrosyliron complexes supported by a β-diketiminate ligand.
Several nitrosyl complexes of Fe and Co have been prepared using the sterically hindered Ar-nacnac ligand (Ar-nacnac = anion of [(2,6-diisopropylphenyl)NC(Me)](2)CH). The dinitrosyliron complexes [Fe(NO)(2)(Ar-nacnac)] (1) and (Bu(4)N)[Fe(NO)(2)(Ar-nacnac)] (2) react with [Fe(III)(TPP)Cl] (TPP = tetraphenylporphine dianion) to generate [Fe(II)(NO)(TPP)] and the corresponding mononitrosyliron co...
متن کاملParamagnetic aluminium β-diketiminate.
The β-diketiminate ligand framework is shown to undergo reduction to form a neutral main group radical stabilized by spiroconjugation of the unpaired electron over the group 13 element centre. The synthesized paramagnetic complex was characterized by EPR spectroscopy and computational chemistry.
متن کاملPreorganized assembly of three iron(II) or manganese(II) β-diketiminate complexes using a cyclophane ligand.
A trinucleating cyclophane bearing three β-diketimine arms, and the corresponding iron(II) and manganese(II) complexes have been synthesized and characterized. The three metal ions are oriented towards the internal void space, and are coordinated by a N2Br2 donor set, in which a unique combination of μ(3), μ, and terminal coordination modes are observed for the halide donors.
متن کاملMononuclear three-coordinate magnesium complexes of a highly sterically encumbered β-diketiminate ligand.
The highly sterically encumbered chelating β-diketiminate ligand, [HC{C(Me)N(2,6-CHPh2-4-MeC6H2)}2](-), (Ar)L(-), has been used to prepare a series of heteroleptic three-coordinate magnesium complexes. Both the bis(imine) and imine-enamine tautomers of the ligand precursor, (Ar)LH, as well as the diethyl ether adduct of the bromide complex [(Ar)LMgBr(OEt2)], the monomeric methyl complex [(Ar)LM...
