Chemistry is a science major with cience and engineering. The main research directions are preparation and modification of special coatings, and research on the structure and performance of functional materials. In a patent, 1293-65-8, name is 1,1′-Dibromoferrocene, introducing its new discovery. Recommanded Product: 1,1′-Dibromoferrocene
We have measured the optical absorption of gaseous ferrocene, 1,1 prime -dimethylferrocene, 1,1 prime -dibromoferrocene, and 1,1 prime -dichloroferrocene using synchrotron radiation. From these data we have estimated the ligand field parameters and noted increasing e//2//g(d) to Cp( pi ) overlap with increasing charge transfer from the Cp ring to the substitution. The optical absorption spectra for ferrocene, dibromoferrocene, and dichloroferrocene are remarkably similar. The halogen substitutions result in greater Cp( pi ) to e//2//g-(d(x2-y2)) hybridization. The e//2//g orbitals become more bonding while the a//1//g and e//1//g orbitals become more non-bonding or antibonding. This change is reflected in a change of the ligand field parameters.
The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.
