An organic electroluminescence device and a compound including nitrogen for an organic electroluminescence device are provided. The compound including nitrogen according to an embodiment of the present disclosure is represented by Formula 1. In Formula 1, “n” is 0 or 1, and M1 and M2 are each independently represented by Formula 2 or 3:
A general and practicalmethod for the construction of various 3,4,5-trisubstituted 1,2,4-triazoles via I2-catalyzed cycloaddition of N-functionalized amidines with hydrazones is reported. This strategy features cheap and readily available catalyst and starting materials, broader substrate scope, and moderate-to-good yields. The mechanism study shows that the existence of hydrogen on the nitrogen of
报道了一种通过 I 2催化N官能化脒与腙的环加成反应构建各种 3,4,5-三取代 1,2,4-三唑的通用且实用的方法。该策略的特点是廉价且易于获得的催化剂和起始材料、更广泛的底物范围以及中等至良好的产率。机理研究表明,腙氮上氢的存在对于这种转变至关重要。
