Question

convert benzyl amide into benzylamine​

Answer 1

Answer:

The most commonly used reagent for this purpose is lithium aluminum hydride (LAH) in THF. If there are no other groups that can be affected by LAH, as in this case, then this is probably the reagent/conditions of choice. However, in cases where greater selectivity is required (e.g., other groups that can undergo reactions with LAH) other reducing conditions can achieve the same result such as hydrosilation (phenyl silane/boronic acid of benzothiophene, triflic anhydride activation followed by treatment with sodium borohydride in THF, others).

                                                                 (or)

To convert benzaldehyde to benzylamine the following reactions take place:

Step 1: Benzaldehyde to benzoic acid by the oxidizing reagent.

Step2: Benzoic acid reacts with ammonia to form benzamide.

Step 3: Benzamide on reduction gives benzylamine.
