“…The large number of available metals and organic molecules that can be used to prepare a MOF leads to a virtually infinite number of possible combinations. This high variability, along with the possibility to introduce new functionalities in a pre-formed MOF by post-synthesis modification [10][11][12], allow to finely tune the chemical compositions, chemical environment and pore structures of the materials and thus, their reactivity. The Lewis acid catalytic properties of MOFs have already been demonstrated for many reactions, including cyanosilylation of carbonyl compounds [13][14][15][16], epoxide methanolysis [17], isomerizations of -pinene oxide and citronellal [18,19], Friedländer condensation [20], alkene cyclopropanation [21], etc.…”

Zirconium-containing metal organic frameworks as solid acid catalysts for the esterification of free fatty acids: Synthesis of biodiesel and other compounds of interest

2015

Zr-containing metal-organic frameworks (MOFs) formed by terephthalate (UiO-66) and 2-aminoterephthalate ligands (UiO-66-NH 2 ) are active and stable catalysts for the acid catalyzed esterification of various saturated and unsaturated fatty acids with MeOH and EtOH, with activities comparable (in some cases superior) to other solid acid catalysts previously reported in literature. Besides the formation of the corresponding fatty acid alkyl esters as biodiesel compounds (FAMEs and FAEEs), esterification of biomassderived fatty acids with other alcohols catalyzed by the Zr-MOFs allows preparing other compounds of interest, such as oleyl oleate or isopropyl palmitate, with good yields under mild conditions. 2

A Cu/PMA–MIL‐101(Cr) metal–organic‐framework‐coated microreactor has been applied in the 1,3‐dipolar cycloaddition of benzyl azide and phenylactetylene (click chemistry). The Cu/PMA–MIL‐101(Cr) catalyst was incorporated by using a washcoating method. The use of tetraethylorthosilicate (TEOS) and a copolymer pluronic F127 as binders resulted in a stable and uniform coating of 6 μm. The application of the Cu/PMA–MIL‐101(Cr) capillary microreactor in the click‐chemistry reaction resulted in a similar intrinsic activity as in the batch reactor, and a continuous production for more than 150 h time‐on‐stream could be achieved. The presence of water in the reagent feed led to reversible catalyst deactivation and was necessary to be removed to obtain a stable catalyst operation.

“…[14][15][16] More sophisticated reactions and stable MOFs suitable for PSM is still being sought not only to enrich the chemical diversity of MOFs but also to functionalize the materials with application-oriented groups. [17][18][19] The copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, a typical 'click' reaction, represents an elegant route for PSM of MOFs. A variety of alkyne- [20][21][22][23][24] and azide-tagged [25][26][27][28] MOFs have been successfully modied by CuAAC reactions.…”

Synthesis and click modification of an azido-functionalized Zr(iv) metal–organic framework and a catalytic study

An azido-functionalized Zr(II) metal-organic framework (MOF), UiO-67-N 3 , was synthesized from 2-azidobiphenyl-4,4 0 -dicarboxylic acid. During the synthesis, the ligand can undergo in situ thermocyclization to give 9H-carbazole-2,7-dicarboxylic acid. It proved that UiO-67-N 3 can be obtained at relatively low temperature without ligand transformation. Post-synthetic modification of UiO-67-N 3 was successfully performed via the click reactions between the azido group and different alkyne compounds to produce new MOFs with different functionalities, UiO-67-Tz-X with X ¼ COOCH 3 , OH and NH 2 . These clicked MOFs, especially UiO-67-Tz-NH 2 , exhibit better stability than the mother material UiO-67-N 3 . The catalytic properties of the clicked MOFs were studied using the Knoevenagel condensation reactions between benzaldehyde and different methylene compounds. Only the NH 2 -functionalized MOF is active, suggesting that the amino group, rather than the triazole group or any other component of the framework, is the crucial active site. The catalysis is heterogeneous. The MOF is recyclable for the reaction with malononitrile but not for the reaction with ethyl cyanoacetate. The deactivation in the latter case is proposed to be because the amino site reacts with the ester group of ethyl cyanoacetate to form amide.
