A range of propargylamines was synthesized via the metal-free decarboxylativecoupling of alkynyl carboxylic acids with amines and paraformaldehyde in water, using a continuous flow reaction system. Aryl- and alkyl-substituted propiolicacids were found to react with secondaryamines in the presence of paraformaldehyde, at 140 °C in water to give the desired propargylamines in good yield.
