1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Recommanded Product: 624-73-7
In 2018,Ali, Safaa H.; Deacon, Glen B.; Junk, Peter C.; Hamidi, Shima; Wiecko, Michal; Wang, Jun published 《Lanthanoid Pseudo-Grignard Reagents: A Major Untapped Resource》.Chemistry – A European Journal published the findings.Recommanded Product: 624-73-7 The information in the text is summarized as follows:
Pseudo-Grignard reagents PhLnI (Ln = Yb, Eu), readily prepared by the oxidative addition of iodobenzene to Yb or Eu metal at -78° in THF or 1,2-dimethoxyethane (DME), react with a range of bulky N,N’-bis(aryl)formamidines to generate an extensive series of LnII or more rarely LnIII complexes, [Eu(DippForm)I(THF)4]·THF (1), [{EuI2(dme)2}2] (2), [Eu(XylForm)I(dme)2]·0.5 dme (3a), [Eu(XylForm)I(dme)(μ-dme)]n (3b), [{Eu(XylForm)I(μ-OH)(THF)2}2] (4), [Yb(DippForm)I(THF)3]·THF (5 a), [Yb(DippForm)I2(THF)3]·2 THF (5 b), [{Yb(MesForm)I(THF)2}2] (6), [{Yb(XylForm)I(THF)2}2] (7a), and [Yb(XylForm)2I(dme)]·dme (7b) {Form = ArNCHNAr; XylForm (Ar = 2,6-Me2C6H3), MesForm (Ar = 2,4,6-Me3C6H2), DippForm (Ar = 2,6-iPr2C6H3)}. Reaction of PhEuI and MesFormH in DME consistently gave 2, and reaction with XylFormH in THF gave 4. Eu complexes 1 and 3a are seven-coordinate divalent monomers, while 3b is a seven-coordinate dme-bridged polymer. Complex 5a of the smaller YbII is a six-coordinate monomer, but the related 6 and 7a are six-coordinate iodide-bridged dimers. 4 Is a trivalent seven-coordinate hydroxide-bridged dimer, whereas complexes 5b and 7b are seven-coordinate monomeric YbIII derivatives A characteristic structural feature is that iodide ligands are cisoid to the formamidinate ligand. To illustrate the synthetic scope of the pseudo-Grignard reagents, [Yb(Ph2pz)I(THF)4] (Ph2pz = 3,5-diphenylpyrazolate) was oxidized with 1,2-diiodoethane to afford seven-coordinate monomeric pyrazolato-Yb(III) iodide [Yb(Ph2Pz)I2(THF)3] (8) in high yield, while metathesis between [Yb(Ph2pz)I(THF)4] and NaCp gave [Yb(C5H5)(Ph2pz)(THF)]n (9), a nine-coordinate η5:η5-Cp-bridged coordination polymer. Reaction of the pseudo-Grignard reagent MeYbI with KN(SiMe3)2 gave [K(dme)4][Yb{N(SiMe3)2}3] (10) with a charge-separated three-coordinate homoleptic [Yb{N(SiMe3)2}3]- anion, a complex that could be obtained in high yield by deliberate synthesis from YbI2 and KN(SiMe3)2 in DME. In addition to this study using 1,2-Diiodoethane, there are many other studies that have used 1,2-Diiodoethane(cas: 624-73-7Recommanded Product: 624-73-7) was used in this study.
