由磁性氧化铁(Fe 3 O 4)纳米颗粒和介孔聚苯胺(mPANI)合成了高表面磁性Fe 3 O 4 @介孔聚苯胺核壳纳米复合材料。在密闭压力反应器中,在高温下通过溶剂热法获得了新型的多孔磁性Fe 3 O 4,从而获得了较大的表面积。通过在多孔磁性Fe 3 O 4上原位表面聚合合成介孔聚苯胺壳在聚乙烯吡咯烷酮(PVP)和十二烷基苯磺酸钠(SDBS)作为连接剂和结构导向剂的情况下,通过“黑莓纳米结构”组装。如各种表征技术所证实的,材料组成,化学计量比和反应条件在这些纳米结构的合成中起着至关重要的作用。中孔聚苯胺壳的作用是稳定多孔磁性Fe 3 O 4纳米颗粒,并提供直接进入核心Fe 3 O 4纳米颗粒的通道。在芳基氯和苯酚的交叉偶联中评估了磁性Fe 3 O 4 @mesoporousPANI纳米复合材料的催化活性。

Betti Base as an Efficient Ligand for Copper-Catalyzed Ullmann Coupling of Phenol with Aryl Halides
Abstract A simple, general, and highly efficient Betti base ligand has been developed for copper-catalyzed Ullmann coupling of phenol with arylhalides without the protection of an inert atmosphere. The reaction proceeds smoothly in the presence of K2CO3 as the base and dimethylsulfoxide as the solvent. The catalyst was reused several times with no evident loss of catalytic activity and is environmentally
