What is the purpose of NaBH4 in the Fluorenone reduction experiment?
What is the purpose of NaBH4 in the Fluorenone reduction experiment?
The ketone in fluorenone can be easily reduced to an alcohol by the action of sodium borohydride. Sodium borohydride (NaBH4) is a common reducing agent that reduces ketones to alcohols. Sodium borohydride can essentially be thought of as a source of hydride ions for the reaction.
Can 9-fluorenone be oxidized further?
Transcribed image text: When the oxidation of 9-fluorenol (white or colorless) is performed, the major product is 9-fluorenone. This is an illustration of the pattern of oxidation of a secondary alcohol to a ketone, which usually is not further oxidized.
What kind of alcohol is 9-fluorenol?
Fluorenol is an alcohol derivative of fluorene. In the most significant isomer, fluoren-9-ol or 9-hydroxyfluorene, the hydroxy group is located on the bridging carbon between the two benzene rings. Hydroxyfluorene can be converted to fluorenone by oxidation. It is a white-cream colored solid at room temperature.
What is the melting point of 9 Fluorenone?
84 °C
Fluorenone/Melting point
Why is it important to exposing sodium borohydride to moisture?
Why is it important to exposing sodium borohydride to moisture? Sodium borohydride is hygroscopic and when it reacts with water it loses a hydride and no longer can be used as a hydride source. 2. Sodium borohydride is a mild reductant, but water can amplify its reactivity and make it too strong of a reductant.
Does sodium borohydride react with water?
At lower pH levels, sodium borohydride reacts exothermically with water to generate flammable hydrogen gas. The heat may ignite the hydrogen, the solvent, and surrounding combustible materials [Haz. SODIUM BOROHYDRIDE is a powerful reducing agent.
What is the function of sodium borohydride?
Sodium borohydride (NaBH4) is a reagent that transforms aldehydes and ketones to the corresponding alcohol, primary or secondary, respectively.
