Through the article, more information about this compound (cas:1273-73-0) is conveyed.

An Et2O solution of (SCN)2 was added slowly to a solution of ferrocene to give a dark brown, unidentified powder, which was not a simple thiocyanate, although ferricinium ions were present. Using CH2 Cl2 as solvent a darkcolored crystalline product [(C5H5)2Fe]2Fe(NCS)4 precipitated Ir spectra showed strong bands at 3095, 1414, 1010, and 850 cm.-1 characteristic of the ferricinium ion and at 2055, 480, and 262 cm.-1 due to the iron thiocyanate group. The electronic spectrum in a KBr disk showed a strong maximum at 20.3 kK with a shoulder at 15.8 kK. An analogous reaction between cobaltocene and (SCN)2 in Et2 O at room temperature yielded as the main product yellow crystalline cobalticinium thiocyanate as shown by elemental anal., ir and electronic spectra, conductivity, and proton N.M.R.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Bromoferrocene( cas:1273-73-0 ) is researched.SDS of cas: 1273-73-0.Tennyson, Andrew G.; Khramov, Dimitri M.; Varnado, C. Daniel; Creswell, Philip T.; Kamplain, Justin W.; Lynch, Vincent M.; Bielawski, Christopher W. published the article 《Indirectly Connected Bis(N-Heterocyclic Carbene) Bimetallic Complexes: Dependence of Metal-Metal Electronic Coupling on Linker Geometry》 about this compound( cas:1273-73-0 ) in Organometallics. Keywords: indirectly connected bis heterocyclic carbene diiron preparation electronic coupling; linker geometry electronic coupling imidazolylidene azido isothiocyanato ferrocene; crystal mol structure electrochem redox imidazolylidene azido isothiocyanato ferrocene. Let’s learn more about 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.
