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
划伤表面:通过胶束和普通表面活性剂的乳液的界面作用,促进了使用两亲性1,3,5-三嗪基铵盐偶联剂的羧酸盐和胺之间的脱氢缩合反应(见图)。阴离子和非离子表面活性剂均能促进羧酸盐的反应,仅非离子表面活性剂可促进胺的反应。在胶束或乳液中观察到对更多亲脂底物的高选择性。
