The Reduction of Aldehydes and Ketones - Chemistry LibreTexts
2023年1月23日 · This page gives you the facts and mechanisms for the reduction of carbonyl compounds (specifically aldehydes and ketones) using sodium tetrahydridoborate (sodium borohydride) as the reducing agent.
Aldehydes and Ketones: 14 Reactions With The Same Mechanism
2017年8月18日 · On paper, NaBH 4 and LiAlH 4 are equally effective in performing the reduction of an aldehyde or ketone to an alcohol. In practice, LiAlH 4 is a much stronger reductant that will also reduce esters and carboxylic acids to alcohols.
REDUCTION OF ALDEHYDES AND KETONES - chemguide
This page looks at the reduction of aldehydes and ketones by two similar reducing agents - lithium tetrahydridoaluminate(III) (also known as lithium aluminium hydride) and sodium tetrahydridoborate(III) (sodium borohydride).
The Wolff-Kishner, Clemmensen, And Other Carbonyl Reductions
2018年8月27日 · The Wolff Kishner reduction of ketones utilizes hydrazine (NH 2 NH 2) as the reducing agent in the presence of strong base (KOH) in a high-boiling protic solvent (ethylene glycol, HO-CH 2 CH 2-OH, boiling point 197 °C).

19.6 Reduction of Aldehydes and Ketones | Organic Chemistry
2021年4月2日 · Chad provides a comprehensive lesson on the reduction of aldehydes and ketones. He begins with hydride reduction using either sodium borohydride (NaBH4) or lithium aluminum hydride (LiAlH4). He...
19.15: Reductions of Ketones and Aldehydes - Chemistry LibreTexts
Aldehydes and ketones can be partially reduced to alcohols with sodium borohydride or Raney nickel. Of course, LiAlH 4 could be used in stead of NaBH 4. However, LiAlH 4 is a stronger reducing agent so some benefits of selectivity are lost.
16.9 Reduction of Aromatic Compounds - Organic Chemistry
Thus, an aryl alkyl ketone prepared by Friedel–Crafts acylation of an aromatic ring can be converted into an alkylbenzene by catalytic hydrogenation over a palladium catalyst. Propiophenone, for instance, is reduced to propylbenzene by catalytic hydrogenation.
Wolff–Kishner Reduction Reaction - ChemTalk
In the Wolff–Kishner reduction, an aldehyde or a ketone is reduced into an alkane. More specifically, the reduction involves the conversion of a carbonyl group (C=O) into a methylene group (–CH 2 –).
