Succinic anhydride, is an organic compound with the molecular formula (CH 2 CO) 2 O. This colorless solid is the acid anhydride of succinic acid. Preparation.
However, under the "many useful applications" described for the products obtained, the use as a size has not yet been mentioned. 30% higher reaction yields were achieved with a pre-cleaned cracked petroleum distillate in an autoclave at 210 °C and it was found that the hydrolysis of the succinic anhydride can already be carried out with steam.

A common way to synthesize an NHS-activated acid is to mix NHS with the desired carboxylic acid and a small amount of an organic base in an anhydrous solvent. A coupling reagent such as dicyclohexylcarbodiimide (DCC) or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) is then added to form a highly reactive activated acid intermediate.
In this reaction, an arene is reacted with succinic anhydride, the subsequent product is then reduced in either a Clemmensen reduction or a Wolff-Kishner reduction. Lastly, a second Friedel-Crafts acylation takes place with addition of acid. [27]
Succinic acid (/ s ə k ˈ s ɪ n ɪ k /) is a dicarboxylic acid with the chemical formula (CH 2) 2 (CO 2 H) 2. [5] In living organisms, succinic acid takes the form of an anion, succinate, which has multiple biological roles as a metabolic intermediate being converted into fumarate by the enzyme succinate dehydrogenase in complex 2 of the electron transport chain which is involved in making ...
A general linear imide functional group. In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. [1] The compounds are structurally related to acid anhydrides, although imides are more resistant to hydrolysis.
Because the aromaticity is not compromised for the flanking rings, anthracene is susceptible to hydrogenation at the 9- and 10- positions. It is produced in the laboratory by dissolving metal reduction using sodium/ethanol, [3] an application of the Bouveault–Blanc reduction.
A common type of organic acid anhydride is a carboxylic anhydride, where the parent acid is a carboxylic acid, the formula of the anhydride being (RC(O)) 2 O. Symmetrical acid anhydrides of this type are named by replacing the word acid in the name of the parent carboxylic acid by the word anhydride. [2] Thus, (CH 3 CO) 2 O is called acetic ...
