DMPAO has been found to be a powerful ligand to enable copper-catalyzed coupling of aryl halides with aliphatic acyclic secondary amines take place under relatively mild conditions, and coupling of aryl halides with primary amines and cyclic secondary amines proceeds at low catalyst loading.

The acid-catalyzed reaction between beta-aminothiophenes and aldehydes, in the presence of selenophenol, leads to alpha-alkyl beta-aminothiophenes. The reduction step is not observed with thiophenol. Without selenol, a second alkylation reaction occurs and bis(3-amino-2-thienyl)methane derivatives are isolated.
