Multiphoton-induced chemistry of phenol in hexane at 266 nm
Year: 1990
Type: article
Abstract: The technique of multiphoton-induced chemistry (MPIC) has been employed to initiate ion-molecule chemistry of phenol in n-hexane solution. The technique involves the use of liquid phase multiphoton ionization (MPI) to prepare organic cations, which then react with the solvent in ion-molecule processes. Products of the ion-molecule chemistry, detected by gas chromatography/mass spectroscopy, are phenoxyphenol and hexyloxybenzene. These products depend upon the square of the laser intensity. It is explicitly shown by pulsed ionization-current measurements, that ionic species are produced as precursors to the observed products. Moreover, positive ion scavengers inhibit the reactivity. Estimates of the rates and quantum yields for the title process are given, as are rate data for the inhibition of the reaction by the ion scavenger, decalin. A brief discussion of the mechanism is also presented.
