2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4) belongs to nitriles. Nitrile function is a very important functional group because it can be manipulated to other functional groups such as carboxylic acid by hydrolysis or amine by reduction, respectively. Alkyl nitriles are sufficiently acidic to undergo deprotonation of the C-H bond adjacent to the CN group.Strong bases are required, such as lithium diisopropylamide and butyl lithium. The product is referred to as a nitrile anion. Application of 55490-87-4

Multicomponent metal-organic frameworks (MOFs) have received an increasing amount of attention due to their potential to produce new topologies, pore metrics, and functionalities compared to MOFs with a single metal cluster and one organic linker. Herein, five isoreticular Zn MOFs were obtained by mixing two types of linear ditopic linkers in a one-pot solvothermal synthesis. Interestingly, in the resulting Zn MOFs a six-connected cyclic trinuclear Zn(II) cluster and an eight-connected linear trinuclear Zn(II) cluster coexist, leading to an uncommon (6,8)-connected network. Catalytic activities toward the solvent-free Knoevenagel reactions were observed for all of these MOFs. Further exptl. and computational studies suggest that they are Bronsted acid-base bifunctional catalysts. Through chem. modifications of dicarboxylate ligands, including their aromatic backbones and substituents, we have successfully implemented reticular chem. for the modulations of pore sizes, surface areas, and catalytic performances in a series of four-component isoreticular MOFs. In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4Application of 55490-87-4).
