(a)
Interpretation:
How the given compound can be produced from an alkene is to be shown.
Concept introduction:
Electrophilic addition of carbenes to
Carbenes are typically highly electrophilic due to the lack of an octet and are
Answer to Problem 12.2P
The given compound can be produced from an alkene is shown below:
Explanation of Solution
The given compound is:
Electrophilic addition of carbenes to alkenes forms cyclopropane rings. Diazomethane (
This carbene intermediate reacts with an alkene in a concerted one-step reaction to form a cyclopropyl ring. The bridge carbon atom in the cyclopropyl ring comes from the carbene while the two carbon atoms are from the original alkene. Two new
The complete reaction of the addition of carbene to alkene is shown below:
The given compound is produced via an electrophilic addition reaction of a carbene to an alkene.
