| 1. | In this tautomer, the proton resides on the ring nitrogen.
|
| 2. | This ketone will prefer to exist in its enol tautomer in solution.
|
| 3. | The imine tautomer is dominant, at least in the solid state.
|
| 4. | Usually the enol is the minority tautomer, but it is more reactive.
|
| 5. | The triol tautomer, which may have aromatic character, predominates in solution.
|
| 6. | In the solid state the hydrazo tautomer forms and several crystal structures exist.
|
| 7. | Small energy difference separates 4-methylimidazole from its tautomer 5-methylimidazole.
|
| 8. | The tele-tautomer is preferred in solution.
|
| 9. | This species exists in equilibrium with a minor tautomer P ( OH ) 3.
|
| 10. | Attempts were also made to predict binding affinities, binding poses and tautomer ratios.
