“…29 There are also other reports on metal complexincorporated mesoporous MCM-41 materials and their various catalytic applications. [30][31][32] Other than mesoporous supports, microporous Y-zeolite was also used widely as a support for various metal complex incorporation. [33][34][35][36][37][38][39] Many reports are available on functionalization and metal complex intercalation to LDH materials leading to forming interesting hybrid materials with enhanced physicochemical properties.…”

“…Polymers like poly(4-vinylpyridine) (P4VP) are advantageous because in addition to being bulky, they enable heterogeneous catalysis − and thus catalyst reuse. Although homogeneous cobalt catalysis for cyclotrimerization has been reported, − to the best of our knowledge, polymer-supported cobalt − has not yet been applied to this reaction. Herein, we report 1,3,5-selective cyclotrimerization using a reusable, stable, heterogeneous, and convoluted polymeric cobalt(II) catalyst under external reducing agent-free conditions (Scheme b).…”

A convoluted poly(4-vinylpyridine) cobalt(II) (P4VP-CoCl2) system was developed as a stable and reusable heterogeneous catalyst. The local structure near the Co atom was determined on the basis of experimental data and theoretical calculations. This immobilized cobalt catalyst showed high selectivity and catalytic activity in the [2 + 2 + 2] cyclotrimerization of terminal aryl alkynes. With 0.033 mol % P4VP-CoCl2, the regioselective formation of 1,3,5-triarylbenzene was realized without 1,2,4-triarylbenzene formation. Further, a multigram-scale (11 g) reaction proceeded efficiently. In addition, the polymer-supported catalyst was successfully recovered and used three times. X-ray photoelectron spectroscopy analysis of the recovered catalyst suggested that cobalt was in the +2 oxidation state. The 1,3,5-triarylbenzene derivatives were applied to the synthesis of a molecular beam electron resist and a polycyclic aromatic hydrocarbon.

“…Al-MCM-48 can be used as heterogeneous acid catalysts, especially for reactions involving bulky molecules which require moderate acid strength [6]. In post-synthesized MCM-48 containing hetero atoms, significant destruction of mesopore structure and short life of active sites are the great drawbacks [7].…”

Mesoporous sieves MCM-48 with hetero atom were synthesized by adding aluminum and titanium sources through hydrothermal method. The results showed that MCM-48 could be synthesized respectively by adjusting exactly the alkalinity of synthesis gel. The conversion rate of DIPB on Al-MCM-48 increased to 80% after 9 h and the selectivity of IPB was 97%. The conversion rate of styrene on Ti-MCM-48 increased to 9% after 8 h and the selectivity of benzaldehyde was 85%. The available active sites, which were introduced by aluminum and titanium atoms, were effectively utilized for catalyst reaction due to the presence of mesopores in Al-MCM-48 and Ti-MCM-48.
