Answer:
The major product formed is a benzyl allyl compound, namely 2-methylene propylbenzene
Explanation:
<u>Part 1.</u>
The product formed from this Wittig reaction with phosphonium ylide is a phenylallyl compound, 2-methylene propylbenzene. Structure and reaction synthesis is attached in file.
<u>Part 2</u>
The types of transformation involved are:
- alkylation (as there is a transfer of alkyl group)
- addition (reaction of ylide)
