Question

Draw the major product(s) or reagents foe the following reactions. Pay attention to stereochemistry where appropriate.

[H], NaBH3CN, ENH2 s try mansen, ents 1. Nang 2. H2 (xs), Pd NH2 1. NaNO2, HCI 2. HBF4 1. HBr, H2O2 2. Nang 3. xs LIAIHA 4. H2O

Answer 1

[H"), NaBH,CN, EINH2 product Explanation: Reaction of ketone with primary amine produces imine as product which on further reduction with NaBH CN produces amine as product. 1. NaN3 NH2 2. H2 (xs). Pd product Explanation: Reaction of primary amine with NaN3 produces azide as product. Reduction of azide with H2, Pd produces amine as product.

1. NaNO2, HCI 2. HBF4 product Explanation: Reaction of aniline with NaNO2, HCl produces diazonium cation which on further reaction with HBF4 produces fluorobenzene as product. 1. HBF, H,02 2. Nang 3. xs LIAIHA 4. H20 product Explanation: Reaction of alkene with HBr, H2O2 produces least substituted alkyl halide as product. Reaction of primary alkyl halide with NaN3 produces azide as product. Reduction of azide with LiAlH4 produces amine as product.
