摘要: Mass spectrometric behaviour of (R)-1-(4-alkylphenyl) alcohols, 1-(4-alkoxylphenyl) alcohols, and 1-(4-alkylthiophenyl) alcohols were studied with the aid of mass-analyzed ion kinetic energy spectrometry under electron impact ionization. All the title compounds show a tendency to eliminate a water molecule to form alkene ions and undergo an a-cleavage to produce protonated aldehyde ions by the loss of alkyl radicals. Except these two common fragment ions, they also show some different fragmentations due to with or without oxy/thioether-linkage.
