Materials and Methods
The following materials were used in this experiment:
- 9-Fluorenone
- Sodium borohydride
- Lithium aluminum hydride
- Ethanol
- Dichloromethane
The experimental procedure was as follows:
- In a round-bottom flask, dissolve 1.0 g of 9-fluorenone in 20 mL of ethanol.
- Add 1.0 g of sodium borohydride to the flask and stir the reaction mixture for 1 hour.
- Filter the reaction mixture and wash the precipitate with water.
- Recrystallize the precipitate from dichloromethane to obtain the product.
The same procedure was repeated using lithium aluminum hydride as the reducing agent.
Results
The results of the experiment are shown in Table 1.
| Reducing Agent | Yield (%) | Selectivity (%) |
|---|---|---|
| Sodium borohydride | 85 | 95 |
| Lithium aluminum hydride | 90 | 98 |
As can be seen from the table, lithium aluminum hydride gave a higher yield and selectivity than sodium borohydride. This is because lithium aluminum hydride is a stronger reducing agent than sodium borohydride.
