A novel adenine-based zinc(II) metal-organic framework featuring the Lewis basic sites for heterogeneous catalysis was written by Zhang, Shixing;He, Hongming;Sun, Fuxing;Zhao, Nian;Du, Jianshi;Pan, Qinhe;Zhu, Guangshan. And the article was included in Inorganic Chemistry Communications in 2017.HPLC of Formula: 55490-87-4 This article mentions the following:
Metal-organic frameworks (MOFs), as a new sort of crystalline materials, have attracted lots of interest in many applications during the past decades. Recently, many efforts were focused on the development of MOFs as heterogeneous catalysis. The authors selected adenine (ad) and tetracarboxylic acid, 5,5′-(1,3,6,8-tetraoxobenzo[Imn] Li et al. (1999), He et al. (2016) phenanthroline-2,7-diyl)bis-1,3-benzenedicarboxylic acid (H4L), as organic linkers to assemble with Zn(II) ions to construct a novel adenine-based porous MOF. There are three different inorganic clusters in the framework, including ZnO2N2, Zn2O2N6, and ZnO5N clusters. Interesting, the resultant porous MOF, [H2NMe2]·[Zn4(L)1.5(ad)3(H2O)2]·4DMF, retains free amino groups in the framework, which can be served as Lewis basic sites to catalyze Knoevenagel condensation reaction. The catalytic study exhibits that the as-synthesized MOF with free amino groups can be used as heterogeneous catalysis with remarkable catalytic efforts and good recycle. CCDC 1501692. In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4HPLC of Formula: 55490-87-4).
2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4) belongs to nitriles. There has been no report on the microbial biosynthesis of nitriles and the physiological function of such enzymes, nor was it not even known whether aliphatic and aromatic nitriles are biological compounds or just petrochemicals. Asymmetric bioreduction of nitriles is an attractive route to produce optically active nitriles as current metal-catalyzed hydrogenations tend to have low reactivity.HPLC of Formula: 55490-87-4
