| Abstract: | The structural principles known to date serving as the basis for the design of heterocyclic compounds with anomalously high
basicity (superbasicity) are reviewed. A general classification is given for such superbases as proton sponges, compounds
that are similar to proton sponges but are not sponges (proton-sponge-like), and proton traps. |
