✦ Synopsis

The ion-molecule reactions of selected hydrocarbon cations with methanol which lead to the production of hydroxylated odd-electron molecular ions in the high-pressure ion source of a mass spectrometer or in the central quadrupole of a tandem quadrupole mass spectrometer are described. A wide variety of hydrocarbon cations were investigated, including aliphatic and aromatic cations; of these, only those having a vacant site on an aromatic system appear to undergo the bydroxylation reaction in high yield. A mechanism is proposed for the formation of the molecular ion of phenol from the ion-molecule reaction involving the phenyl cation with methanol. In addition, thermochemical data are provided which support the formation of the postulated species.
