In the gas phase, (CH 3 ) 3 SiOSi Y (CH 3 ) 2 and (CH 3 )CH 2 SiOSi Y (CH 3 ) 2 ions 1 and 2 were formed in the external source of a Fourier transform ion cyclofrom resonance (FT-ICR) spectrometer by electron impact ionization of (CH 3 ) 3 SiOSi(CH 3 ) 3 . In the FT-ICR cell, the electrophilic cente
