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.
