WebStep 2: 2-Phenoxy-1-phenylethanone (1.1089 g, 5.2 mmol) was dissolved in 35 mL of methanol. Sodium borohydride (0.3534 g, 10.4 mmol) was added portion-wise. After addition the mixture was stirred at room temperature for 2 h. Excess sodium borohydride was quenched with careful addition of saturated aqueous NH4Cl solution (30 mL). WebSodium borohydride (NaBH 4) is the most commonly available borohydride, synthesized by reacting methylborate with sodium hydride in mineral oil. It is employed as a precursor for producing other metal borohydrides. Various approaches for qualitative and quantitative monitoring of sodium borohydride have been explained. [ 1]
