It is un fortunate that building in an aldehyde function by 'direct' methods is generally not easy, so that methods have been sought for many years for the conversion of carboxylic acids and a variety of their derivatives into the corresponding aldehydes by direct reduction (similarly, many ...

This serves as a way toindirectly reduce carboxylic acids to aldehydes. You can convert the carboxylic acid to an acid chloride using something like SOCl2or PCl3, and thenreducethe acid chloride to the aldehyde with LiAlH[OC(CH3)3)]3 What is the advantage of using LiAlH(Ot-Bu)3, relative...
Reactions of aldehydes and ketones: oxidation reduction nucleophilic addition 1) Aldehydes are easily oxidized, ketones are not. 2) Aldehydes are more reactive in nucleophilic additions than ketones. alkane alcohol aldehyde ketone carboxylic acid oxidation reduction reduction addition product nucleophilic addi...

Alcohol, aldehyde, and carboxylic acid are closely related families of chemicals. These chemicals, and their derivatives, are vastly useful in almost all aspect of modern chemical industry, producing solvents, fuels, active pharmaceutical ingredients (APIs), preservatives. In the last few decades, ...

The conversion of methanol over zeolites offers a sustainable alternative for fuels and chemicals production. However, a complete understanding of the competing reaction pathways, particularly those leading to C-C bond formation, remains elusive. This wo
