The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Bromoferrocene(SMILESS: Br[C-]12[Fe+2]3456789([C-]%10C6=C7C8=C9%10)C1=C3C4=C25,cas:1273-73-0) is researched.Synthetic Route of C9H9NO4S. The article 《Indirectly Connected Bis(N-Heterocyclic Carbene) Bimetallic Complexes: Dependence of Metal-Metal Electronic Coupling on Linker Geometry》 in relation to this compound, is published in Organometallics. Let’s take a look at the latest research on this compound (cas:1273-73-0).
Reaction of 1,1′,3,3′-tetra(tert-amyl)benzobis(imidazolylidene) (1) with 2 equivalent of FcN3 or FcNCS afforded bisadducts [(FcN3)2(1)] (2) or [(FcNCS)2(1)] (3), resp. (Fc = ferrocene). These represent the first examples of complexes comprising metals indirectly connected to the carbene atoms of N-heterocyclic carbenes (NHCs) via their ligand sets. Cyclic and differential pulse voltammetry indicated that bis(NHC) 1 facilitated significant electronic coupling between ferrocene centers in 2 (ΔE = 140 mV), but not in 3. The different degrees of electronic interaction are due to geometric factors: the triazene linker in 2 is nearly coplanar with the bis(NHC) scaffold, whereas the isothiocyanate linker is orthogonal, as determined by x-ray crystallog. Employing this “”indirect connection”” strategy should enable tuning of metal-metal interactions by simple alteration the organic linker between NHC and MLn fragments rather than complete redesign thereof. Given that NHC-reactive azide or isothiocyanate groups can be incorporated into both organic and inorganic compounds, this approach is envisioned to facilitate access to otherwise inaccessible catalysts and materials.
