A simple, convenient, transition metal-free one pot synthesis of 3,5-disubstituted-1,2,4-triazoles has been established. The innovation in this reaction is the use of easily available 1,1-diaminoazines as substrates. This method provides the products with wider substrate scope, at an expedited rate, and with relatively better yields in comparison to the reported methods. The reaction mechanism involves
已经建立了一种简单、方便、不含过渡金属的 3,5-二取代-1,2,4-三唑的一锅合成方法。该反应的创新之处在于使用容易获得的 1,1-二氨基嗪作为底物。与报道的方法相比,该方法以更快的速度为产品提供了更广泛的底物范围和相对更好的产量。反应机理包括初始分子间亲核加成(由 I 2促进),然后是分子内亲核环化。
