Step by step solution

01

Step-by-Step Solution Step 1: Use of organocuprate

The organocuprate is used in many nucleophilic substitution reactions to get products such as aldehydes and ketones.

They attack the electrophilic carbon center of any acid chloride structure where chlorine is a powerful leaving group.

02

Choosing the right organocuprate

To obtain the correct organocuprate reagent, you require the retrosynthetic pathway.

The ester and Grignard reagent needed to prepare ketone a. are:

Synthesis of a.

The ester and Grignard reagent needed to prepare ketone b. are:

Synthesis of b.

The ester and Grignard reagent needed to prepare ketone c. are:
