以易得的胺、碳二亚胺和锌(OTf)(2)为原料，通过简单的一步反应，首次合成了三取代三氟化胍。X-射线分析表明，它们采用了一维链状或新颖的三维氢键网络，这是以前在胍盐固体结构中未见报道的。双核锌络合物的分离及其随后的碳二亚胺插入为深入了解三氟化胍的形成机理提供了线索。
The first synthesis of trisubstituted guanidinium triflates has been achieved by a simple one-step procedure from readily available amines, carbodiimides, and Zn(OTf)(2). X-ray analysis revealed they adopt 1-D chain-like or novel 3-D hydrogen-bonded networks, which have not been reported previously in the solid structure of guanidinium salts. Isolation of a binuclear zinc complex and its subsequent carbodiimide insertion provide the insight into the mechanism for the formation of guanidinium triflates.
