Synthesis of Amides from Amines and Esters Under Hydrothermal Conditions [PDF]
ChemistryOpen, Volume 15, Issue 2, February 2026.In this study, we explore the amide synthesis under hydrothermal conditions, using amines and esters as the starting materials. Proposed major pathway starts with ester hydrolysis, followed by condensation between carboxylic acids and amines. The amide yield is dependent on the substrate structure, solution pH, and the presence of dissolved metal salts.
