acid anhydrides with ammonia or primary amines - chemguide
The first product this time is called an N-substituted amide. If you compare the structure with the amide produced in the reaction with ammonia, the only difference is that one of the hydrogens on the nitrogen has been substituted for a methyl group. This particular compound is N-methylethanamide.
N-substituted Amides - (Organic Chemistry) - Fiveable
Definition. N-substituted amides are a class of organic compounds derived from amides, where the hydrogen atom on the nitrogen is replaced by a substituent group. These compounds are important in organic chemistry, particularly in the context of reactions involving amines.
N-substituted amides - (Organic Chemistry II) - Fiveable
N-substituted amides are a class of organic compounds formed by replacing one hydrogen atom of the amine group in an amide with an alkyl or aryl group.

21.7: Chemistry of Amides - Chemistry LibreTexts
Proteins can be considered to consist of amino acid residues joined by amide (or peptide) links. These peptide links consist of exactly the same structural units that we find in N‑substituted primary amides. A lactam is a cyclic amide, in the same way that a lactone is a cyclic ester:
Amide: Definition, Structure, Nomenclature, and Examples
The fundamental structure of an amide consists of a carbonyl group (C=O) bonded to a nitrogen atom (N) with a single bond, and the nitrogen atom is also bonded to two additional substituents, typically hydrogen atoms (H).

2023年11月24日 · According to IUPAC, the secondary amide shown above should be referred to as an N‑substituted primary amide, and the tertiary amide should be referred to as a N, N‑disubstituted primary amide. IUPAC reserves the term …
Kinetics and mechanism of N-substituted amide hydrolysis in …
2010年1月1日 · N-methylacetamide (NMA) served as a model to investigate the hydrolysis kinetics and mechanism of N-substituted amides in high-temperature water. The major products are acetic acid and methylamine, and the reaction is reversible.
A mild protocol for the alkaline hydrolysis of secondary and tertiary amides in non-aqueous conditions, by the use of NaOH in methanol/dichloromethane or methanol/dioxane (1:9) at room temperature or under reflux, has been developed and a …
Primary Amide - an overview | ScienceDirect Topics
Primary amides, secondary amides, and imides can be substituted at the nitrogen with alkyl or aryl radicals. The resulting compounds are known as N-substituted amides (or N-substituted imides). The nature of the N-substituent and that of the acyl radical influence the …
