Biomimetic model for [FeFe]-hydrogenase: asymmetrically disubstituted diiron complex with a redox-active 2,2'-bipyridyl ligand.
[FeFe]-hydrogenases feature a unique active site in which the primary catalytic unit is directly coordinated via a bridging cysteine thiolate to a secondary, redox active [4Fe4S] unit. The goal of this study was to evaluate the impact of a bidentate, redox non-innocent ligand on the electrocatalytic properties of the (μ-S(CH(2))(3)S)Fe(2)(CO)(4)L(2) family of [FeFe]-hydrogenase models as a prox...
متن کاملReactions of a β-diketiminate zinc hydride complex with heterocumulenes.
The β-diketiminate zinc hydride MesnacnacZnH (1) reacts with CO(2), C(Ni-Pr)(2) and t-BuNCO at ambient temperature with insertion into the Zn-H bond and subsequent formation of the corresponding formato (2), formamido (3) and formamidinato (4) complexes.
متن کاملCu–O2 adduct supported by a b-diketiminate ligand?†
The finding that dioxygen binds end-on to the CuB site in the crystal structure of a precatalytic complex of peptidylglycine a-hydroxylating monooxygenase has spurred the search for biomimetic model complexes exhibiting the same dioxygen coordination. Recent work has not only indicated that sterically hindered b-diketiminate ligands (L) could support side-on 1 : 1 Cu–O2 adducts, but also that a...
متن کاملChemistry 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 کاملAn iron(ii) hydride complex of a ligand with two adjacent β-diketiminate binding sites and its reactivity.
After lithiation of PYR-H2 (PYR = [(NC(Me)C(H)C(Me)NC6H3(iPr)2)2(C5H3N)](2-)) - the precursor of an expanded β-diketiminato ligand system with two binding pockets - with KN(TMS)2 the reaction of the resulting potassium salt with FeBr2 led to a dinuclear iron(ii) bromide complex [(PYR)Fe(μ-Br)2Fe] (1). Through treatment with KHBEt3 the bromide ligands could be replaced by hydrides to yield [PYR)...
