Abstract
The electronic structure of pentafluorophenyl-substituted silanes ArnSi(CH3)4-n (Ar = C6H5, C6F5, 4-FC6H4, 2,3,5,6-F4C5N; n = 1; Ar = C6H5, C6F5, n = 2, 4) was studied by X-ray emission and He(I) photoelectron spectroscopy. The He(I) photoelectron spectra were measured and interpreted on the basis of MNDO calculations, analysis of the p-fluoro effect, and relative intensities. Substitution of C6F5 for C6H5 in aryltrimethyl- and diaryldimethylsilanes results in enhanced π interaction between the aryl and Si(CH3)n groups (n = 2, 3) by higher π levels and has almost no effect on the charge on the silicon atom.
