Abstract

The chemical properties of an extremely twisted amide are examined quantitatively for the first time. The predicted high basicity of 2-quinuclidonium is confirmed experimentally by measuring the gas-phase proton affinity using the extended kinetic method. Fragmentation of this molecule further reveals that the lack of resonance stabilization weakens the amide bond. Furthermore, a new route for synthesizing 2-quinuclidonium by eliminating water is demonstrated in the gas phase.
