| 31. | DFT-determined geometry for the transition state of the above reaction.
|
| 32. | This result is consistent with the 5-membered cyclic transition state.
|
| 33. | The products that is, in order to reach the transition state for the reaction.
|
| 34. | The reaction proceeds through the 6-membered transition state shown below.
|
| 35. | Repulsion between the negative charges would raise the energy value near the transition state.
|
| 36. | Cram s rule explains the stereoselectivity by considering the transition state depicted in figure 3.
|
| 37. | This type of comparison is especially useful because most transition states cannot be characterized experimentally.
|
| 38. | This action stabilizes the enediol intermediate and the other transition states on the reaction pathway.
|
| 39. | Carbocation rearrangement reactions occur through three-center bond transition states.
|
| 40. | It has been shown that the transition state is a planar six member transition state.
