| 11. | The formation of the trans isomer would have indicated that the intermediate carbanion was unstable.
|
| 12. | Stabilization of the resultant carbanion is provided by the S ( O ) R group.
|
| 13. | She also researched carbanion reactivity, with emphasis on reactivity and structure of ion pairs.
|
| 14. | Styrene reacts in toluene with sodium to 1, 3-diphenylpropane through the intermediate carbanion:
|
| 15. | The initial stereochemistry of the reaction sequence is established in the step where the carbanion attacks the carbonyl.
|
| 16. | Therefore, due to the Arg219, the PLP-stabilized carbanion intermediate is less likely to form.
|
| 17. | Many carbanion synthons, as drawn, present stability issues that render the molecule s existence in reality impossible.
|
| 18. | One further relevant point is that the first organic correlation diagrams were in a 1961 publication on carbanion rearrangements.
|
| 19. | The C2 of this ring is capable of acting as an acid by donating its proton and forming a carbanion.
|
| 20. | This unique combination of contacts and conformations of TPP leads to formation of the reactive C2-carbanion, eventually.
