Selective CO2 adsorption and Lewis acid catalytic activity towards naphthimidazole synthesis by a Zn-MOF was written by Agarwal, Rashmi A.;De, Dinesh. And the article was included in Polyhedron in 2020.Application In Synthesis of Pyridin-4-ol This article mentions the following:
A two-fold interpenetrated, three dimensional Zn-based porous MOF, {[Zn(BPBA)Cl]·5H2O}n (1) [BPBA = 3,5-bis-(4-oxo-4H-pyridin-1-yl)-benzoate], has been synthesized at high temperature under solvothermal conditions by the in situ acidic hydrolysis of the tripodal ligand 3,5-bis-(4-oxo-4H-pyridin-1-yl)-benzonitrile (BPBN). The de-solvated MOF exhibited selective CO2 adsorption at 195 K and 1 bar pressure over N2 and H2. Interestingly, the four coordinated Zn(II) sites in the MOF exhibited high Lewis acidic heterogeneous catalytic activity for the synthesis of naphthimidazole in excellent yield without pre-activation of the MOF. The Zn(II) sites could directly coordinate to the substrate to catalyze the chem. transformation by an expansion of the coordination number The π-π supramol. interactions between the aromatic rings of the framework and the substrate mol. might help in the substrate activation. In the experiment, the researchers used many compounds, for example, Pyridin-4-ol (cas: 626-64-2Application In Synthesis of Pyridin-4-ol).
Pyridin-4-ol (cas: 626-64-2) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Application In Synthesis of Pyridin-4-ol
