Department of Chemistry, The University of Adelaide, South Australia 5005



The lecture will include some of our recent work concerning closed-shell organic negative ions, together with the mechanisms of the intramolecular reactions they undergo when energised. Four areas will be covered.
  1. Simple fragmentations of negative ions. Analytical applications.

  2. Negative ion cleavages of peptides. Analytical applications.

  3. 'Charge-remote' reactions of negative ions: do they really occur? Systems to be described:- (i) the 8-nonenoate anion, and (ii) disubstituted adamantanes.

  4. The gas phase Wittig rearrangement of benzyl ethers. An unexpected mechanism. A joint experimental/potential surface study.
