摘要：

Electron donation by the trimethylsilyl group has been determined, through X-ray photoelectron spectroscopic analysis of the transition-metal center of zirconocenes, hafnocenes, and ferrocenes having trimethylsilyl substituents on the cyclopentadienide rings, to decrease the binding energy of the inner-shell electrons of the complexed transition metal by 0.10 eV/trimethylsilyl group. The trimethylsilyl group is slightly more electron donating than the methyl group in these systems.
