To synthesize benzyl alcohol from benzaldehyde, we can use the following retrosynthesis pathway:1. Benzaldehyde + NaBH4 Benzyl alcoholHere's the step-by-step synthesis:Step 1: Reduction of Benzaldehyde to Benzyl AlcoholReagents: Sodium borohydride NaBH4 Solvent: Methanol MeOH or ethanol EtOH Reaction conditions: Room temperature, stirring for 1-2 hoursProcedure:1. Dissolve the benzaldehyde in an appropriate amount of methanol or ethanol in a round-bottom flask.2. Add sodium borohydride to the solution slowly, with stirring. The reaction is exothermic, so the temperature should be monitored and maintained at room temperature.3. Stir the reaction mixture for 1-2 hours at room temperature.4. After the reaction is complete, quench the reaction mixture with water or dilute acid e.g., 1M HCl to decompose any unreacted sodium borohydride.5. Extract the product benzyl alcohol using an organic solvent e.g., diethyl ether or dichloromethane .6. Dry the organic layer over anhydrous sodium sulfate Na2SO4 to remove any residual water.7. Filter the drying agent and evaporate the solvent to obtain the pure benzyl alcohol product.This one-step reduction of benzaldehyde to benzyl alcohol using sodium borohydride is a simple and efficient method for synthesizing benzyl alcohol.
