Unusual Bond Activations
The unusual reactivity of hafnocene complexes in comparison to their titanium and zirconium analogues was dramatically demonstrated in the recent functionalization of coordinated N2 and the coupling of CO2 and N2 to a substituted hydrazine product. The differences in their structure and bonding were also noticed; for example, the s and p ratio of the diene bonding in (s-cis-h-diene) metallocene...
متن کاملElectron transfer collisions with spatially oriented CH 3 CN Sean
Positive and negative ion pairs are detected in collisions of fast [5È30 eV center of mass (CM)] K atoms with molecules oriented in space. Di†erent products are favored by attack at di†erent ends of the molecule. 3 The principal negative ion is CN~, which is produced preferentially upon attack at the negative, or CN-end of the molecule. The cyanomethyl ion, is observed as the energy is raised, ...
متن کاملDistance dependence of through-bond electron transfer rates in electron-capture and electron-transfer dissociation
Ab initio electronic structure calculations on model cations containing a disulfide linkage and a protonated amine site are carried out to examine ow the rate of electron transfer from a Rydberg orbital on the amine site to the S S * orbital depends upon the distance between these two rbitals. These simulations are relevant to both electron-capture and electron-transfer dissociation mass spectr...
متن کاملSteric Effects in Electron Transfer from Potassium to -Bonded Oriented Molecules CH
Electron transfer from K atoms to oriented CH3CN, CH3NC, and CCl3CN is studied in crossed beams at energies near the threshold for forming an ion pair. For the methyl compounds, the dominant ions are K+ and CN-; the steric asymmetry is very small and energy-independent, characteristic of sideways attack with the electron apparently entering the π*CN antibonding orbital. Migration of the electro...
متن کاملHalogen bond-assisted electron transfer reactions of aliphatic bromosubstituted electrophiles.
Isolation of pre-reactive complexes and analysis of kinetics of redox reactions of tetrabromomethane and tribromonitromethane demonstrated that halogen bonding results in significant lowering of the activation barriers for electron transfer, and that the rate constants of such (inner-sphere) processes can be evaluated from spectral, structural, and thermodynamic characteristics of the halogen-b...
