Notes:
The mass spectra of pentafluorobenzyl- and pentafluorophenylethylsilanes show cleavage to give cyclic fluorohydrocarbon ions of the tropylium type, which, with their fragmentation products, are the principal charge carrying species. In pentafluorophenyldimethylsilanes, exchange of fluorine and methyl between silicon and carbon occurs readily, and again the spectrum is dominated by cyclic fluorohydrocarbon ions. The composition and relative intensities of characteristic ions of diagnostic value in the spectra of pentafluorophenyldimethylsilanes are listed.
