21. He received a chiral molecules, and synthesized the highly stable 8-cycloheptatrienylheptafulvenyl carbocation . 22. This leads to the trans carbocation intermediate. 23. The carbocation escapes into another phase, driving carbocation formation to the right . .. 24. The carbocation escapes into another phase, driving carbocation formation to the right . .. 25.

Olah of the United States for his contributions to carbocation chemistry. 28. 1994 _ George A . Olah, United States, for his contributions to carbocation chemistry. 29. Prior to hydride transfer, the carbocation intermediate is liable to undergo Wagner-Meerwein rearrangements. 30. The resulting C12 carbocation can continue to react with an olefin to form a larger carbocation.
