Silica nanoparticles immobilized benzoylthiourea ferrous complex as an efficient and reusable catalyst for one-pot synthesis of benzopyranopyrimidines

Rational surface silane modification for immobilizing glucose oxidase

“…APTES was usually integrated onto silica nanoparticles, and then the amino group of APTES reacted with the carboxyl groups on the surface of GOx [21][22][23]. In this research, GOx was firstly modified with APTES and then immobilized by inorganic sol-gel physical entrapment.…”

Fe3O4/MIL‐101(Fe) nanocomposite as an efficient and recyclable catalyst for Strecker reaction

“…Thus, MOF crystals are uniformly enclosed by Fe 3 O 4 NPs to form a homogeneous magnetic product, defined as Fe 3 O 4 /MIL‐101(Fe). Continuously, as part of our previous studies to investigate catalytic performance of new heterogeneous nanocomposites, we have examined the catalytic efficiency of a kind of MOF structure, combined with amino‐modified core‐shell magnetic NPs, in order to extend merits of an environmentally‐friendly metal catalyst to accomplish bond‐forming processes. Indeed, we have shown that catalytic resources could comprise in a single architecture to intensify the catalytic function, in which is anticipated individually, for synthetic methodologies.…”

Synthesis, Characterization, and Heterogeneous Catalytic Activity of Sulfamic Acid Functionalized Magnetic IRMOF‐3

“…However, the best yields were achieved with cyclic secondary amines such as morpholine, piperidine and 4‐methyl piperidine. All products are known compounds,, and found to be identical with authentic samples through melting points and spectroscopic data. Almost all the reactions worked quite well and the desired products were obtained in good to high yields and reasonable turnover numbers (TON) within sustainable reaction times.…”
