In heterogeneous catalysis, the catalyst is in a different phase from the reactants. SDS of cas: 1273-94-5, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1273-94-5, name is 1,1′-Diacetylferrocene. In an article£¬Which mentioned a new discovery about 1273-94-5
ELECTRONIC STRUCTURE OF FERROCENE DERIVATIVES STUDIED BY He(I) PHOTOELECTRON SPECTROSCOPY AND CNDO/2 METHOD
The effect of substituents in the Cp ligands on the electronic structure has been studied for the 1,1′-disubstituted ferrocenes Fe(CpX)2, with X = C2H5, OCH3, CN, COCH3, COOCH3, OOCCH3, CH2C6H5, or C6H5, by UV photoelectron spectroscopy and by CNDO/2 calculations.The energy gap between the 2E2g and 2A1g ion states, 0.36 eV in the parent ferrocene, is affected only by the COCH3 and COOCH3 substituents, which lower it to 0.22 and 0.28 eV, respectively.Splitting of e1u(?) level due to the lowering of the symmetry is the only effect observed in the photoelectron spectra.There is a strong conjugation between the phenyl and cyclopentadienyl ?-orbitals in 1,1′-diphenylferrocene.The changes in the a1g(d) ionization energy calculated by the DeltaSCF method using CNDO/2 total energies are in a good agreement with the experimental data.
