The alcohol products were isolated after aqueous workup in good to excellent yields (63-100%). The lithium, sodium, boron and aluminium end up as soluble inorganic salts at … Introduction: This was a reduction reaction in whish camphor was reduced into isoborneol with the use of sodium borohydride. Sodium borohydride methanolysis is an alternative for hydrogen production from sodium borohydride and has a number of advantages over hydrolysis reactions in terms of by-product handling. NaBH4 reduces many organic carbonyls, depending on the precise conditions. So all we have time for this video is sodium borohydride.
