ELECTRON-SPIN RESONANCE INVESTIGATIONS OF THE NEGATIVE IONS OF FOUR ORGANOSILICON COMPOUNDS
Abstract
Electron-spin resonance spectra of the negative ions of 4-biphenylytriphenylsilane, di-(4-biphenylyl)diphenylsilane, tetraphenylsilane and tetra-4-biphenylylsilane have been recorded. The unpaired electron is located almost exclusively on the biphenyl substituent in the first radical, but is thought to exchange rapidly between all groups in the third. It has not been possible to etermine the electron distribution in the second and fourth. An analogous all-carbon compound, tetraphenylmethane, is spontaneously reduced to the non-magnetic dinegative ion, which is stable only at low temperature and rearranges rapidly at room temperature to produce the biphenylyl mononegative ion.
