Collisional activation and metastable ion characteristics

Collisional activation and metastable ion characteristics. 52. Formation of ethylenebenzenium and protonated benzocyclobutene, but not .alpha.-phenylethyl, cations from the ionization of gaseous .beta.-phenylethyl halides. Koeppel, Claus; McLafferty, F. W. (Spencer T. Olin lab., Cornell Univ., Ithaca, N. Y., USA). J. Am. Chem. Soc., 98(25), 8293-4 (English) 1976. CODEN: JACSAT. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Unimol. gas-phase decompn. of PhCH2CH2R+.bul. (I; R = Cl, Me) in the collisional-activation mass spectrometer gave protonated benzocyclobutene ion (II) and an unknown compd. (III) formed by the isomerization of II or ethylenebenzenium ion (IV); PhCH+Me and IV were not obsd. I (R = Br, iodo) under similar conditions gave III and IV. The ratio of the C7H7+ to C8H9+ concns. in the normal mass spectra of PhCH2CH2R (R = Br, Cl, Me, iodo) indicated that at low energies CH2-CH2 bond cleavage was preferred over CH2-R cleavage; CH2-R cleavage to give PhCH2CH2+ which isomerized to II or IV was preferred at higher energies. 31835-62-8 and 17376-04-4 are just another two chemicals used in this study. The effect of R on the anchimeric assistance necessary to form II and IV was discussed. .
