Interaction of Fullerenes with Organosilanes in the Ionization Chamber of a Mass Spectrometer under Electron Impact and the Reaction of C₆₀ with Tetraphenylsilane in Solution under UV Irradiation

Figure 1

Electron ionization mass spectra in the high mass range from experiments in the IC of a mass spectrometer with C₆₀ and (a) tetramethylsilane (1), (b) tetraphenylsilane (4), and (c1 and c2) α-naphthylphenylmethylsilane (5): (c1) one-scan mass spectrum and (c2) monoisotopic (¹²C, ¹H) spectrum derived from the spectrum obtained by peak-summarizing over 101 magnetic scans (the background peaks have been deleted), (d) diphenylmethylsilane (3), (e) diphenylsilane (2), and (f) with C₇₀ and silane 1.
