It provides plenty of detailed and useful information in the practical aspects of the oxidation of alcohols to aldehydes and ketones, which is probably the most important reaction in the synthesis
Aldehydes and Ketones. Key Information & Summary. The aldehydes are organic compounds that have a formyl group, indicated by -CHO. Usually, the keto form is more stable than the enol. This equilibrium allows ketones to be prepared via the hydration of alkynes.
Aldehydes and ketones undergo a variety of reactions that lead to many different products. Grignard reagents, organolithium compounds, and sodium alkynides react with formaldehyde to produce primary alcohols, all other aldehydes to produce secondary alcohols, and ketones to Lesson covers the ozonolysis of alkenes and hydration of alkynes methods to form aldehydes and ketones.
The acid-catalyzed hydration of Alkynes forms enols according to the Markovnikov’s rule which undergo keto-enol tautomerization to produce ketones. The final product of this reaction, however, is a ketone: Let’s start with internal alkynes. The first step is the protonation of the triple bond forming a
