Web-Reduces aldehydes to 1° OH, and ketones to 2° OH -Excellent yields -Selective: usually does not react with carbonyl groups that are less reactive than ketones & aldehydes (carboxylic acids and esters are unreactive toward borohydride reduction) WebBoren 2 (0.00217 mol/0.00064 mol) x 100 = 337% Discussion: In the experiment, the reduction of a ketone, 9-fluorenone, using a metal hydride to yield a secondary alcohol, 9-fluorenol, was demonstrated. Sodium borohydride was used as the reducing agent due to its ability to rapidly react with the carbonyl group thus will reduce the ketone to an …
Sodium Borohydride Reduction of Benzoin Introduction
WebBorohydride Reduction of Ketones 5 the IR of estrone but not in the IR of estradiol . We do observe the loss of this - C = O stretch peak in the IR of our product . We can conclude that our product does not contain any estrone due to the loss of this peak . 5 . The mechanism performed in this experiment is drawn to the left . WebFor the reduction of aldehydes and ketones, many different reducing agents are available. However, the most convenient and least expensive is probably sodium borohydride (NaBH 4). This reagent does not require very dry reagents and solvents like the very useful but much more reactive LiAlH 4 does. In fact, NaBH 4 may be used in aqueous solution. tamarack women\u0027s snow boots
