Acid-base reactions between amines and carboxylic acids in hexane
Abstract: The reactions of carboxylic acids (HX) and amine bases (B) were studied in the solvent hexane at 250 using the differential vapor pressure method
A map of the amine–carboxylic acid coupling system
2 avr. 2020 The coupling of an amine with a carboxylic acid to form an amide bond is the most popular chemical reaction used for drug discovery1.
Direct Synthesis of Amides from Carboxylic Acids and Amines Using
16 avr. 2013 The reactions also typically require relatively dilute reaction conditions. Stoichiometric boron reagents for amidation often require anhydrous ...
Direct Amide Formation Between Carboxylic Acids and Amines
The most desirable solution to this problem of amide formation is the direct condensation i.e. by direct reaction between an amine and a carboxylic acid.
