Hydrates, Hemiacetals, and Acetals – Master Organic Chemistry
2010年5月28日 — An acetal (sometimes called a ketal if originating from a ketone) contains a carbon with two single bonds to OR groups. Hydrates and hemiacetals are in equilibrium with their respective aldehydes and ketones. Acetals are formed through treatment of an aldehyde or ketone with an alcohol in the presence of (anhydrous) acid.
Acetal - Wikipedia
Acetal is a functional group with the connectivity R2C (OR')2, derived from aldehydes or ketones and alcohols. Learn about the synthesis, properties, applications and examples of acetals and related compounds such as sugars, formaldehyde, acetonide and polyoxymethylene.
17.8: Acetals as Protecting Groups - Chemistry LibreTexts
Acetals are stable and unreactive derivatives of aldehydes and ketones that can be used to protect them from nucleophilic reagents. Learn how to form and deprotect acetals, and compare them with other protecting groups such as thioketals and silyl ethers.
19.10: Nucleophilic Addition of Alcohols - Acetal Formation
Learn how aldehydes and ketones react with alcohols to form acetals and hemiacetals, and how to use acid catalysts and molecular sieves to control the reaction. See examples, mechanisms, and biological applications of these functional groups.
19.10 Nucleophilic Addition of Alcohols: Acetal Formation
Learn how aldehydes and ketones react with alcohols in the presence of acid to form acetals, which are useful protecting groups for carbonyl compounds. See mechanisms, examples, and problems on acetal formation and cleavage.
