Question

Identify the reagents necessary to accomplish the following transformations: Choose from the following list of reagents: 1) x

Answer 1

Answer #1

The solution is given below :

Step A = i, simple bromine addition occur to the double bond.

Step B = a, debromination occur by NaNH₂ and alkyne is formed.

Step C = b, oxidised to give aldehyde.

Step D = f , Me^(-) attacks at the carbonyl carbon and there after one proton is abstracted from the water and 1° alcohol is formed.

Step E =g , oxidation occur and ketone is produced.

Step F = h , water addition in double bond.

Step G = i , primary alcohol to aldehyde by pyridinium chlorocromate and methylene chloride.
