  可重复使用的钴基纳米催化剂在醇脱氢偶联策略中的应用：喹喔啉和亚胺支架的合成

  摘要：

  报道了氮掺杂的碳负载的钴催化的亚胺和喹喔啉基序的有效合成。与在不同温度下制备的其他材料相比，Co（OAc）2-苯/碳800（Co-phen / C-800）在通过二胺和二醇之间的偶联合成喹喔啉中显示出优异的反应活性。此外，应用转移氢化和无受体脱氢偶联策略，由硝基化合物合成了亚胺和喹喔啉衍生物。该方案的实际适用性已通过克级合成和高达第8个循环的催化剂可重复使用性证明。此外，进行了一些动力学实验以实现可能的机理。

  The inexpensive and simple NiBr2/1,10-phenanthroline system-catalyzed synthesis of a series of quinoxalines from both 2-nitroanilines and 1,2-diamines is demonstrated. The reusability test for this system was performed up to the seventh cycle, which afforded good yields of the desired product without losing its reactivity significantly. Notably, during the catalytic reaction, the formation of the heterogeneous

  The present disclosure relates to the technical field of organic materials, and provided therein is a nitrogen-containing compound, comprising at least three directly or indirectly linked fused ring systems. A first fused ring system is a fluorenyl group spiro-linked by adamantane, and adamantyl can greatly increase the electron cloud density of a conjugated structure of the first fused ring system by means of a hyperconjugation effect, which can increase hole mobility. The three fused ring systems enable the nitrogen-containing compound of the present disclosure to have a high first triplet energy level so that the nitrogen-containing compound of the present disclosure is suitable as the host material of an organic light-emitting layer in an organic electroluminescent device. Further provided in the present disclosure are an organic electroluminescent device comprising the described nitrogen-containing compound and an electronic apparatus, and the described nitrogen-containing compound can improve the performance of the organic electroluminescent device.

  efficient synthesis of imines and quinoxaline motifs is reported. Co(OAc)2-Phen/Carbon-800 (Co-phen/C-800) showed the superior reactivity compared to other materials prepared at different temperature, in the synthesis of quinoxalines by the coupling between diamines and diols. Moreover, applying the transfer hydrogenation and acceptorless dehydrogenative coupling strategy, imines and quinoxaline derivatives
