Electron impact studies. LXXXIX. Nucleophilic substitution at carbonyl centres. Acetic anhydride. An ion cyclotron resonance study

Abstract

The gas phase reaction between the acetate anion and acetic anhydride yields a 1 : 1 adduct, which may decompose by loss of ketene. The extent of these reactions depend upon both the sample pressure and the transit time of ions in the cell. Power absorption maxima are obtained for electron beam energies of 0 eV, 4 eV and values in excess of 10 eV.
