Question
Which reducing agent is commonly used in reductive amination of aldehydes/ketones to amines?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Sodium cyanoborohydride (NaBH3CN) is selective for reductive amination because it reduces iminium ions at pH ~6-7 without reducing aldehydes/ketones rapidly under those conditions.
Hint
Works well at mildly acidic pH.
