Free Electron Transfer from Xanthenyl- and Fluorenylsilanes (Me3 or Ph3) to Parent Solvent Radical Cations: Effects of Molecule Dynamics

Autor: Karakostas, N., Naumov, S., Siskos, M. G., Zarkadis, A. K., Hermann, R., Brede, O.

Parent radical cations of nonpolar solvents (alkanes and alkyl chlorides) ionize 9-(trimethylsilyl)xanthenes and 9-(trimethylsilyl)fluorenes in a diffusion-controlled electron transfer. The actual electron jump as the deciding part of the process doe

Autor: Brede, O., Hermann, R., Naumov, S., Zarkadis, A. K., Perdikomatis, G. P., Siskos, M. G.

The rotation motion of a larger substituent of an aromatic ring is accompanied by the electron density fluctuation of the highest occupied molecular orbitals. For benzyltrimethylsilanes p-R-3-C6H4-(sic)-CR1-R2(SiMe3) [R-3 = H,PhCO; R-1, R-2 = H,H; H,

Indication of molecular oscillations during free electron transfer: reaction of butyl chloride parent ions with benzyltrimethylsilanes

Autor: Brede, O., Hermann, R., Naumov, S., Perdikomatis, G. P., Zarkadis, A. K., Siskos, M. G.

Molecular oscillations are accompanied with electron density fluctuations mainly of the higher occupied orbitals. This is particularly marked for rotational motions of large substituents of aromatic molecules. Hence, the extremely rapid and non-adiab
