| 31. | The resulting C12 carbocation can continue to react with an olefin to form a larger carbocation.
|
| 32. | _1994 : George A . Olah, United States, for his contributions to carbocation chemistry.
|
| 33. | The more substituted the carbocation, the more stable it is, due to induction and hyperconjugation.
|
| 34. | A 1, 3-hydride shift then takes place to give a more stable allylic carbocation.
|
| 35. | This carbocation intermediate can readily undergo rearrangements, which can lead to a complex mixture of products.
|
| 36. | Acetic acid is often used as a solvent for reactions involving carbocations, such as rearranged carbocation.
|
| 37. | This reactivity is due to the relative stability of the tertiary and secondary carbocation over the primary carbocations.
|
| 38. | With a stereogenic center next to the carbocation the substitution can be stereoselective in intra and intramolecular reactions.
|
| 39. | A rearrangement reaction of the carbocation follows with ring closure to "'9 " '.
|
| 40. | Alkyl substitutions on the olefins have been seen to increase the reaction rate by stabilizing the resulting carbocation.
