Design and synthesis of a new magnetic metal organic framework as a versatile platform for immobilization of acidic catalysts and CO₂ fixation reaction

Abstract

The first report of the use of an acidic magnetic metal organic framework for the chemical fixation of CO2 as an environmentally friendly reaction.

Robust {Cd4}-Organic Framework for Efficiently Catalyzing CO2 Cycloaddition and Knoevenagel Condensation

“…In terms of recently published references, activated MOFs show catalytic performance on Knoevenagel condensation due to their Lewis acid and base sites in the confined hole microenvironment. − Given that there are rich active sites including open metal sites, carboxyl oxygen atoms, free pyridine groups, Me 2 NH 2 + , and μ 3 -OH groups, the heterogeneous catalytic performance of NUC-67a on Knoevenagel condensation was studied. First, as shown in Table , a mixture of 20 mmol of malononitrile and 10 mmol of benzaldehyde in a three-necked flask with 0.1 mol % NUC-67a was stirred for 12 h, which resulted in a 45% yield of benzylidenemalononitrile (entry 2).…”

A highly robust cluster-based indium(iii)–organic framework with efficient catalytic activity in cycloaddition of CO2 and Knoevenagel condensation

“…Besides, the activation energy of the Knoevenagel condensation reaction calculated using the Arrhenius equation was 37.6 kJ mol −1 . 69…”

“…Besides, the activation energy of the Knoevenagel condensation reaction calculated using the Arrhenius equation was 37.6 kJ mol −1 . 69 Under the optimal reaction conditions, a series of aldehyde derivatives differentiated by their substituents in terms of steric hindrance and electron effects were selected to check the catalytic generality of NUC-66a, as shown in Table 4. The 1 HMR spectra of the resulting products are shown in Fig.…”

Synthesis and catalytic application of a curcumin‐based bio‐MOF in one‐pot preparation of tetrahydroquinazolinone derivatives via Biginelli reaction

“…[7][8][9][10][11] In recent decades, enormous attempts have been paid to design and construct the new types of potent porous solid catalysts which are envirofriendly. [12][13][14] In this point of view, MOFs have a unique position, especially when using environmentally friendly bio-based linkers such as amino acids and curcumin. MOFs show a broad panel of pore sizes (up to 94% empty spaces), shapes, and designable catalytic activities.…”
