The article was titled 《Synthesis and characterization of η6-arene(halogenidoaluminato)lanthanoid(II) and alkaline earth(II) complexes》, and you may find the article in Polyhedron.Electric Literature of C2H4I2 The information in the text is summarized as follows:

η6-Arene(iodidoaluminato)lanthanoid(II) complexes, {[Ln(η6-C6H5Me)(AlI4)2]}n [Ln = Sm, 1, Eu, 2, Yb, 3; C6H5Me = toluene] have been prepared by reactions of in situ generated aluminum triiodide with the corresponding lanthanoid metals and 1,2-diiodoethane in toluene (molar ratio: 2:1:1). Compounds 1-3 are polymeric and the lanthanoid(II) atom of 1 and 2 is coordinated by an η6-arene and three chelating κ (I, I’) tetraiodidoaluminate ligands, two of which are also bridging (LnI2AlI2Ln) and one is terminal. 3 Is coordinated by an η6-arene, one terminal chelating κ (I, I’) and one chelating and bridging (YbI2AlI2Yb) tetraiodidoaluminate ligand, and one monodentate tetraiodidoaluminate ligand, which is also bridging (YbIAl(I)I2Yb). These are the first x-ray crystal structures of arene(tetrakisiodidoaluminato)lanthanoid(II) complexes. The first reported alk. earth(II) (η6-arene)iodidoaluminate complexes, namely [Ca(η6-C6H5Me)(AlI4)2]n (4), {[Sr(η6-C6H5Me)(AlI4)2]n·nPhMe} (5), [Ba(η6-C6H5Me)2(AlI4)2] (6), [Ca(η6-C6H3Me3-1,3,5)(AlI4)2]n (7) and {[Sr(η6-C6H3Me3-1,3,5)(AlI4)2]n·0.5n(PhMe3)} (8) have also been obtained in an arene (toluene or mesitylene) solution by a similar method. Complex 4 is isocoordinate with 3, and 5 is isomorphous with 2. Complex 7 has eight coordinate Ca similar to 4, and complex 8 has nine coordinate Sr as in 5. Mononuclear ten coordinate complex 6 is the first example of a monomeric η6-arene sandwich complex of barium. The EuII bromidoaluminate complex {[Eu(η6-C6H5Me)(AlBr4)2]n·0.5nPhMe} (9) has been prepared from Eu metal, AlBr3, and BrCH2CH2Br in toluene and has a unit cell similar to 8 despite the different metal and arene. In the part of experimental materials, we found many familiar compounds, such as 1,2-Diiodoethane(cas: 624-73-7Electric Literature of C2H4I2)

1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. Organic iodides are used in veterinary products (Organic Iodide Powder) as a nutritional source of iodine. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs. Oceanic alkyl iodides are believed to be the principal source of atmospheric iodine.Electric Literature of C2H4I2

The article was titled 《Indole Inhibitors of MMP-13 for Arthritic Disorders》, and you may find the article in ACS Omega.Synthetic Route of C5H4IN The information in the text is summarized as follows:

Here, we described the design, by fragment merging and multiparameter optimization, of selective MMP-13 inhibitors that display an appropriate balance of potency and physicochem. properties to qualify as tool compounds suitable for in vivo testing. Optimization of potency was guided by structure-based insights, specifically to replace an ester moiety and introduce polar directional hydrogen bonding interactions in the core of the mol. By introducing polar enthalpic interactions in this series of inhibitors, the overall beneficial physicochem. properties were maintained. These physicochem. properties translated to excellent drug-like properties beyond potency. In a murine model of rheumatoid arthritis, treatment of mice with selective inhibitors of MMP-13 resulted in a statistically significant reduction in the mean arthritic score vs. control when dosed over a 14 day period.

Wei, Rong-Jia; Zhou, Hou-Gan; Zhang, Zhi-Yin; Ning, Guo-Hong; Li, Dan published their research in CCS Chemistry in 2021. The article was titled 《Copper (I)- organic frameworks for catalysis: networking metal clusters with dynamic covalent chemistry》.COA of Formula: C5H4IN The article contains the following contents:

Metal clusters exhibit diverse structures, emerging functions, and applications; thus, incorporating clus- ters into metal-organic frameworks (MOFs) brings tremendous merits. Although the construction of cluster-based MOFs is sophisticated, the reticular materials constructed from a combination of the chem. of metal clusters and covalent organic frameworks (COFs) remain unexplored. Herein, we prepared two Cu(l) cluster-based MOFs with cyclic trinuclear units (CTUs), termed JNM-1 and JNM-Z, either by a stepwise synthetic approach or by a one-pot reaction, for networking clusters with dy- namic covalent chem., rarely utilized in MOF syn- thesis. The generated JNMs exhibited excellent stability and could be used as recyclable catalysts for palladium-free Sonogashira coupling reactions with high efficiency and tolerance (>90% yield for nine examples), without loss of performance for at least five cycle runs. In addition, conjugated single molec- ular wires with lengths ranging from 1.6 to 2.7 nm were synthesized feasibly using the JNM-1 catalyst.

Wang, Miao; Saad, Ali; Li, Xiaoguang; Peng, Tao; Zhang, Qi-Tao; Kumar, Mohan; Zhao, Wei published an article in 2021. The article was titled 《Solid-state synthesis of single-phase nickel monophosphosulfide for the oxygen evolution reaction》, and you may find the article in Dalton Transactions.Electric Literature of C4H4INO2 The information in the text is summarized as follows:

High-performance and cost-effective nonprecious-metal catalysts are essential for the next-generation oxygen evolution reaction (OER). However, the electrocatalysis of the OER during water splitting is often carried out by using noble metal catalysts, such as RuO2 or IrO2 with high-cost and limited stability. Herein, we reported a successful synthesis of a ternary nickel monophosphosulfide (NiPS) compound via a simple solid-state route and further investigated its electrocatalytic performances for water oxidation It is found that the NiPS electrocatalyst exhibits good OER performance in 1.0 M KOH solution, i.e., achieving a c.d. of 20 mA cm-2 at an overpotential of 400 mV and a Tafel slope of 126 mV dec-1, comparable to com. benchmark RuO2. The ternary NiPS electrocatalyst for the OER is superior to its binary counterparts, i.e., Ni2P and NiS. D. functional theory (DFT) calculations combined with ex situ XPS were performed to obtain further insights into the intrinsic catalytic mechanism of NiPS, and their results clearly revealed that the instability of the Ni=O intermediate during the OH* → O* process and the easy oxidation of the (PS)3- anion favoring the formation of hydroxyl-based species (i.e., Ni(OH)2/NiOOH) on the surface of the catalyst, which plays a crucial role in facilitating the OER activity. Furthermore, we creatively extended this method to the fabrication of heteroatom substituted catalysts and a new quaternary CoNiP2S2 compound was successfully synthesized for the first time in the same way. The structural properties and electrocatalytic performance towards the OER for CoNiP2S2 (e.g., 20 mA cm-2 at 376 mV) are also systematically investigated in this work.1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Electric Literature of C4H4INO2) was used in this study.
