Electron donation capability of the trimethylsiloxy substituent as studied by photoelectron spectroscopy and electron spin resonance of polysubstituted benzene derivatives
Poly(trimethylsiloxy)-substituted benzenes were studied by UV photoelectron (PE) spectroscopy. The obsd. ionization energies show that the OSiMe3 group is a stronger donor than the Me group but a weaker donor than OMe or CH2SiMe3 groups. Highly substituted derivs. yield radical cations on oxidn. with AlCl3/CH2Cl2/Me3SiCl, the ESR and PE results indicating dominating nO/p interaction, with little or no sO-Si/p hyperconjugation, for the radical-cation ground state. on SciFinder(R)
