In chemistry, an acyl group is a moiety derived by the removal of one or more hydroxyl groups from an oxoacid, [1] including inorganic acids. It contains a double-bonded oxygen atom and an organyl group (R−C=O) or hydrogen in the case of formyl group (H−C=O).

Carboxylic acid derivatives tend to undergo a reaction called nucleophilic acyl substitution. In the same fashion as nucleophilic addition, this mechanism starts with a nucleophilic attack on an electrophilic carbonyl carbon, forming a tetrahedral alkoxide intermediate.

May 6, 2011 · Nucleophilic acyl substitution is a reaction where a nucleophile forms a new bond with the carbonyl carbon of an acyl group with accompanying breakage of a bond between the carbonyl carbon and a leaving group.

→What is an acyl group in chemistry? In chemistry, an acyl group is a functional group consisting of a carbonyl group (C=O) attached to an alkyl or aryl group. Acyl groups are derived from carboxylic acids and are found in various chemical compounds, including esters, …

Aug 12, 2019 · The saponification process derives its name from the ancient craft of soap-making, in which the ester groups of triacylglycerols in animal fats are hydrolized under basic conditions to glycerol and fatty acyl anions (see section 2.5A for a reminder of …

Jul 20, 2022 · A nucleophilic acyl substitution reaction starts with nucleophilic attack at the carbonyl, leading to a tetrahedral intermediate (step 1 below). In step 2, the tetrahedral intermediate collapses and the acyl X group is expelled, usually accepting a proton from an enzymatic acid in the process.

Acylation definition involves a chemical reaction in which an acyl group (-RCO) is introduced into a molecule. This process typically involves the replacement of a hydrogen atom in an organic compound with an acyl group, often through the use of …

A nucleophilic acyl substitution reaction involves the substitution of a nucleophile for a leaving group in a carboxylic acid derivative. Identify the leaving group (Cl – in the case of an acid chloride) and the nucleophile (an alcohol in this case), and replace one by the other.
