Scratch the surface : Dehydrocondensations between carboxylates and amines by using an amphiphilic 1,3,5‐triazinylammonium‐based coupling agent were accelerated by the interfacial effect of micelles and emulsions of common surfactants (see figure). The reaction of carboxylates was promoted by both anionic and nonionic surfactants, and that of amines was promoted by only a nonionic surfactant. High selectivities for more lipophilic substrates were observed in micelles or emulsions.
