(iii) From acid derivatives All acid derivatives like amides (RCONH 2), acid halides (RCOCl), esters (RCOOR‟), acid anhydrides (RCO-O-COR) on hydrolysis give carboxylic acids. All acid derivatives break from RCO+. (iv) From nitriles and amides Nitriles are hydrolysed to amides and then to acids in the presence of H+or OH-as catalyst. Mild ...

Coupling Reagents - Peptide

prepare amides, esters and acid anhydrides from carboxylic acids. These reagents can also convert primary amides to nitriles, which can be useful in organic synthesis but is a troublesome ... Carbodiimide activation of amino acid derivatives often causes a partial racemization of the amino acid. In peptide synthesis, adding an equivalent of 1 ...

Ch 06 Amines and Amides - Angelo State University

• Amines are organic derivatives of ammonia, NH3, in which one or more of the three H’s is replaced by a carbon group. • Amines are classified as primary (1°), secondary (2°), or tertiary (3°), depending on how many carbon groups are connected to the nitrogen atom.
