Abstract
Acetone chemical ionization mass spectra of 14 monosubstituted aromati c compounds were studied. Benzene, toluene and halobenzenes give exclu sively charge-exchange spectra with very little fragmentation. Protona tion is characteristic of compounds with higher proton affinities than acetone, with the exception of benzonitrile. Acetylation reactions ar e observed mainly with benzonitrile, phenol, anisole and aniline. The acetylation of phenol and aniline mostly occurs at the substitutent.
