Amides can be reduced to amines by LiAlH4: Remember that the reduction of all the other carboxylic acid derivatives containing a carbonyl group produces alcohols: Another exception is the nitriles, but these do not contain a … Read more
Preparation of Amides Amides can be prepared from acyl chlorides, esters, and carboxylic acids. The most straightforward should be the reaction with acid chlorides since they are the most reactive carboxylic acid derivatives, and amines are good nucleophiles too. This … Read more
Reduction of Acyl Chlorides to Alcohols Acid chlorides can be reduced to alcohols by lithium aluminum hydride (LiAlH4) and sodium borohydride (NaBH4). In both reactions, there is an aldehyde intermediate formed, and therefore, the reducing agent is used … Read more
Alcohols can be prepared from carbonyl compounds such as aldehydes, ketones, esters, acid chlorides, and even carboxylic acids by hydride reductions. These reductions are a result of a net addition of two hydrogen atoms to the C=O bond: … Read more
In the previous post, we discussed the reduction of carbonyl compounds such as aldehydes, ketones, acids, esters, and acid chlorides, covering the appropriate reducing agents, the step-by-step mechanisms, and key concepts involved in these transformations. This post serves as a … Read more
Alcohols can be prepared by reduction of aldehydes, ketones, esters and other carbonyl containing compounds. There are dozens of reagents such as LiAlH4, BaBH4, DIBAL for reducing carbonyls to alcohols. Each of these reagents has advantages and disadvantages. Some are … Read more
