Hossain, Elius Md; Guo, Zhifang; Wang, Jun; Deacon, Glen B.; Junk, Peter C.; Diether, Dominic; Anwander, Reiner published an article in 2022. The article was titled 《η6-Arene(halogenidoaluminato)lanthanoid(III) Complexes: Synthesis, Characterization and Catalytic Activity for Isoprene Polymerization》, and you may find the article in European Journal of Inorganic Chemistry.Recommanded Product: 1,2-Diiodoethane The information in the text is summarized as follows:
η6-Arene(iodido-/bromido-aluminato)lanthanoid(III) complexes, [Ln(η6-C6H5Me)(AlI4)3] [Ln = La (1), Ce (2), Nd (3), (Gd) (4); C6H5Me = toluene], [Ln(η6-C6H3Me3-1,3,5)(AlI4)3] [Ln = La (5), Ce (6), Pr (7), Nd (8), Sm (9), Gd (10); C6H3Me3-1,3,5 = mesitylene], and [Ln(η6-C6H5Me)(AlBr4)3] [Ln = La (11), Nd (12), Sm (13)] were prepared by reactions of aluminum triiodide or aluminum tribromide with the corresponding lanthanoid metals and 1,2-diiodoethane or 1,2-dibromoethane in an arene (toluene or mesitylene) solution (molar ratio : 6 : 2 : 3). The first x-ray crystal structures of arene(iodidoaluminato)lanthanoid(III) complexes are reported. The lanthanoid atom is coordinated by an η6-arene and three chelating κ(I, I’)-tetraiodidoaluminato ligands. The tetrabromidoaluminate complexes have similar structures. The precatalyst 3 was treated with AlR3 (R = Me or iBu) to give [Nd(η6-C6H5Me)(AlI3R)3] species in situ, which were then tested for catalytic activity towards isoprene polymerization Although the resulting polyisoprene had a desirable high cis-1,4 content, the catalyst performance was well below known best performing systems and indicates that iodidoaluminates are the least favorable of the halogenidoaluminatolanthanoid(III) complexes. In the part of experimental materials, we found many familiar compounds, such as 1,2-Diiodoethane(cas: 624-73-7Recommanded Product: 1,2-Diiodoethane)
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.Recommanded Product: 1,2-Diiodoethane
