Nomenclature of Amides

30 04 2013En revanche pourriez-vous m'clairer sur la nomenclature des amides secondaires et tertiaires? J'avais trouv une explication sur le net mais en y regardant de plus prs je pense qu'amides primaires substitues et amides secondaires ou tertiaires taient confondues Auriez-vous une explication simple ou un lien me donner vers un site qui expliquerait la nomenclature des amides All amides can form hydrogen bonds with water Amides with 1-5 carbon atoms are soluble in water * Hydrogen Bonding of Amides O || CH3—C—N—H | H Hydrogen bonding occurs between primary amides O || CH3—C—N—H | H * Amides undergo: Acid hydrolysis to produce a carboxylic acid and ammonium salt Base hydrolysis to produce the salt of

Chapter 20: Carboxylic Acid Derivatives: Nucleophilic Acyl

Synthesis of Amides: Amides are most commonly prepared from the reactions of ammonia 1 or 2 amines with acids chlorides acid anhydrides or esters This is a nucleophilic acyl substitution reaction When an acid chloride or anhydride is used a mol of acid (HCl or carboxylic acid) is produced Since amines are bases a

Amides are different why? because –NH 2 is such a poor leaving group! Nitriles are ALSO different why? because they don't HAVE a leaving group! • these examples how that the synthesis of amides and nitriles is connected to the synthesis of amines which we need to know for the next section of the notes AND therefore is also connected to the synthesis of carboxylic acids

Amides - Structure and Classification The amide is better represented as a dipolar ion: C O N C O N Because the bond between the carbonyl carbon atom and the nitrogen atom has a partial double bond character the bond angles about the carbonyl carbon atom and nitrogen atom are both close to 120 (sp2 hybridization) The dipolar ion nature of the amide bond is very important in determining the

When naming amides we follow the same pattern of naming for esters except: 1 Any alkyl groups attached to the nitrogen gets listed as "N-methyl" "N-ethyl" "N-propyl" etc 2 The parent chain starts at the carbonyl carbon and is counted moving away from the amide nitrogen When naming acid anhydrides: 1 Determine the length of

Nomenclature 2 • Nomenclature • Primary amines are – Amines versus Amides • Amides are much less basic than amines – The pKa of a protonated amide is typically about zero • One reason for this much lower basicity is that the amide is greatly stabilized by resonance but the protonated amide is not • A more important reason for the weaker basicity of amides is that the nitrogen

These recommendations extend rule 3AA-19 5 of the Nomenclature and Symbolism for Amino Acids and Peptides (Recommendations 1983) to cover all classes of cyclic peptides They include rings generated from an acyclic peptide by formation of a peptide or ester bond by a disulfide link or by a new carbon carbon carbon-nitrogen nitrogen-oxygen or carbon-sulfur bond (not esters or amides) These

Amides: Amides are as well derivatives of carboxylic acids This time the carboxylic acid is related with an ammonia or amine Since with esters the parent carboxylic acid is recognized This is then known as an alkanamide and involves the nitrogen atom For instance linking ethanoic acid along with ammonia provides ethanamide

Nomenclature for amines divides into two basic components: one for alkyl substitution of the nitrogen atom and one for aryl substitution In the former case the relevant suffix is -amine molecules where other functional groups are present the prefix amino-is used In the latter case the base molecule is aniline Some examples are shown below When the nitrogen has more than one alkyl
