Synthesis of 1,2,4-Triazoles,<i>N</i>-Fused 1,2,4-Triazoles and 1,2,4-Oxadiazoles<i>via</i>Molybdenum Hexacarbonyl-Mediated Carbonylation of Aryl Iodides
protocol has been developed for the synthesis of 1,2,4‐triazoles, N‐fused 1,2,4‐triazoles and 1,2,4‐oxadiazoles using molybdenum hexacarbonyl where, for the first time, molybdenum hexacarbonyl acts as a convenient and reliable solid source of carbon monoxide. This procedure provides an easy access to a library of 1,2,4‐triazole, N‐fused 1,2,4‐triazole and 1,2,4‐oxadiazole derivatives in fair to good

The present disclosure relates to a novel compound and an organic electroluminescent element including the same, and the compound according to the present disclosure is used for an organic material layer of the organic electroluminescent element, thereby improving the light emitting efficiency, driving voltage, lifetime, and the like of the organic electroluminescent element.
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。
