The synthesis of 1,1′-bis(N-tert-butyl-N-hydroxyamino)ferrocene (1) is described, and the x-ray anal. showed eclipsed positions of the two tert-butylhydroxyamino groups. This structure can be explained by the interactions of the hydroxyl hydrogens with the N atoms of the other tert-butylhydroxyamino group. This interaction is maintained in solution and may explain that the oxidation of 1 using Ag2O gave a decomposition reaction instead of the expected 1,1′-bis(N-tert-butylaminoxy)ferrocene. The ESR spectrum of an oxidized solution of 1 showed a 1:1:1 triplet, but it corresponded only to traces of an N-O• radical. Cyclic voltammograms of 1 showed that it is more easily oxidized than ferrocene and less easily than 1,1′-diaminoferrocene, indicating that chem. oxidation of 1 occurs in the ferrocenyl part of the mol., followed by rapid decomposition

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.

Compound: Bromoferrocene, is researched, Molecular C10BrFe, CAS is 1273-73-0, about Cofacial metallocenes. Synthesis and crystal structure of 1,8-diferrocenylnaphthalene.

The optimal synthesis of 1,8-differocenylnaphthalene (I) was the coupling of 1,8-diiodonaphthalene and ferrocenylzinc chloride in the presence of ferrocenylphosphine-containing catalyst PdLCl2, giving 58% of I with 94% selectivity. The x-ray crystal structure of I showed that the naphthalene ring and bonds from the peri-C atoms to the cyclopentadienyl rings were highly distorted. The 2 substituted cyclopentadienyl rings were rotated by ∼46° from the perpendicular to the naphthalene ring. Cyclic voltammetry of I showed 2 reversible, one-electron waves. The monocation I+BF4- derived by oxidation of I with AgBF4, had an intervalence transfer band at 1600 nm (εmax 200), not shown by the corresponding dication of I. I+ was best represented as a weakly interacting mixed-valence system.

The iron 2p and carbon 1s near-edge x-ray absorption fine structure (NEXAFS) spectra of substituted ferrocene compounds, Cp2Fe, Cp*2Fe, CpFe(η5-C5H4Me), CpFe(η5-C5H4Br) CpFe(η5-C5H4CO2H) CpFe(η5-C5H4CH:CH2) (η5-C5H4Me)2Fe, (η5-C5H4Br)2Fe, (η5-C5H4CO2H)2Fe, (η5-C5H4COMe)2Fe are reported and are interpreted with the aid of EHMO (EHMO) theory and d. functional theory (DFT). Significant substituent effects are observed in both the Fe 2p and C 1s NEXAFS spectra. These effects can be related to the electron donating/withdrawing properties of the cyclopentadienyl ligands and their substituents as well as the presence of π* conjugation between the cyclopentadienyl ligand and unsaturated substituents.
