In this study, we try to develop an effective route to the preparation of hollow mesoporous boron nitride spheres (HMBNS) with surface decorated by CuO for the synthesis of some heterocyclic [3,3,3] propellane derivatives under green conditions. Hollow boron nitride spheres were synthesized using the carbon spheres (as a primary template) through the reaction of boric acid and urea follow by surface decoration with CuO. The carbonic template was removed by thermal treatment and hollow boron nitride spheres/CuO (HBNS/CuO) was prepared. In addition to boron and nitrogen which have catalytic role, loading of CuO on the boron nitride shell surfaces, creates a special bifunctional acid-base catalyst to synthesis of heterocyclic [3,3,3] propellane derivatives. The structure of prepared catalyst was characterized by FT-IR, XRD, XPS, BET, FE-SEM, EDX and TEM methods and the influence of the catalyst activity was explored for the synthesis of heterocyclic [3,3,3] propellane derivatives in water media at room temperature. Green conditions, easy recovery of catalyst as well as high to excellent yield of products are some of the merits of presented method.

在这项研究中，我们试图开发一种有效的途径来制备具有 CuO 装饰的空心介孔氮化硼球 (HMBNS)，用于在绿色条件下合成一些杂环 [3,3,3] 丙烷衍生物。使用碳球（作为主要模板）通过硼酸和尿素反应合成空心氮化硼球，然后用CuO进行表面装饰。通过热处理去除碳模板并制备空心氮化硼球/CuO（HBNS/CuO）。除了具有催化作用的硼和氮外，在氮化硼壳表面负载CuO，形成了一种特殊的双功能酸碱催化剂，用于合成杂环[3,3,3]丙烷衍生物。采用FT-IR、XRD、XPS、BET、FE-SEM、探讨了 EDX 和 TEM 方法以及催化剂活性对室温下在水介质中合成杂环 [3,3,3] 丙烷衍生物的影响。绿色条件、催化剂易于回收以及产品的高收率是所提出方法的一些优点。
