Q9-7P a
Question
How would you prepare the following carbonyl compounds starting from an alkyne (reddish brown Br)?
Step-by-Step Solution
Verified Answer
Answer
1Step 1: Hydroboration – oxidation reaction
The hydroboration–oxidation to the direct, mercury(II)-catalyzed hydration reaction. Direct hydration with aqueous acid and mercury(II) sulfate leads to a methyl ketone,
2Step 2: Formation of compound a
Terminal alkyne undergoes two additions, giving a doubly hydroborated intermediate.
