Zheng, Jianwei published the artcileNovel core-shell nanocomposite as an effective heterogeneous catalyst for the synthesis of benzimidazoles, SDS of cas: 2622-67-5, the publication is Nanotechnology (2021), 32(26), 265603, database is CAplus and MEDLINE.
An effective heterogeneous catalyst for the synthesis of benzimidazole by integrating acidic catalytic activity and promoted the aerobic oxidation and magnetic recyclability of core-shell nanocomposite Fe3O4@SiO2@UiO-66 was designed. The Fe3O4@SiO2 core was encapsulated by the in-situ-grown UiO-66 shell and the UiO-66 shell retains the porous structure and crystallinity of UiO-66 with abundant exposed Lewis acid sites. It showed high catalytic ability for the synthesis of various benzimidazoles through the acid-catalyzed condensation and aerobic oxidation with in-situ oxygen. The Fe3O4@SiO2 core provided magnetic recyclability of Fe3O4@SiO2@UiO-66 and maintains high catalytic ability and stability over six cycles.
