《Regioselective Cross-Electrophile Coupling of Epoxides and (Hetero)aryl Iodides via Ni/Ti/Photoredox Catalysis》 was published in ACS Catalysis in 2020. These research results belong to Parasram, Marvin; Shields, Benjamin J.; Ahmad, Omar; Knauber, Thomas; Doyle, Abigail G.. Electric Literature of C7H7I The article mentions the following:

A cross-electrophile coupling reaction of epoxides and (hetero)aryl iodides that operates via the merger of three catalytic cycles involving a Ni-, Ti-, and organic photoredox catalyst has been developed. Three distinct classes of epoxides, styrene oxides, cyclic epoxides, and terminal aliphatic epoxides, underwent coupling in moderate to good yield and high regioselectivity with the use of three different nitrogen-based ligands for Ni under otherwise identical reaction conditions. The mild reaction conditions accommodate a broad scope of abundant and complex coupling partners. Mechanistic studies suggest that when styrene oxides are employed radical intermediates are involved via Ti-radical ring opening of the epoxide. Conversely, for terminal aliphatic epoxides, involvement of an iodohydrin intermediate enables the formation of the unexpected linear product.

And the article was published in ChemistrySelect in 2019. Quality Control of 1-Bromo-4-iodobenzene The author mentioned the following in the article:

An efficient methodol. was developed for C-N cross-coupling reaction between aryl halides and amines using a catalytic system comprised of CuI and N,N-dimethylaminopyridine (DMAP). Coupling reactions were carried out in DMSO at 120°C in the presence of 5 mol% CuI, 20 mol% DMAP and 2.5 equiv of KOH. Addition of DMAP was found to be beneficial in significantly accelerating the reaction rate. Both aryl iodides and aryl bromides were successfully coupled with different primary and secondary amines to furnish the desired cross-coupling product in high yield. A copper complex [Cu(DMAP)4I]I, made by combining CuI and DMAP, was found to produce superior results for the Buchwlad-Hartwig cross-coupling reaction. The use of 2 mol% of the copper complex was sufficient to produce high yields of product.

Hyeok published 《Bis-imidazolium iodide organic ionic plastic crystals and their applications to solid state dye-sensitized solar cells》.Organic Electronics published the findings.Safety of 1,2-Diiodoethane The information in the text is summarized as follows:

Novel dicationic bis-imidazolium iodide salts have been discovered as new organic ionic plastic crystalline materials. Most of them show multiple solid-solid phase transitions below their melting temperatures Their phase transition temperatures are dependent on the imidazolium cation structure. According to Timmermans’ definition of plastic crystals, bis-imidazolium iodide salts with either n-heptyl or n-octyl side arms can be classified as “”true plastic crystals”” because of their low ΔSf values (<20 J mol-1 K-1). The bis-imidazolium iodide salts are stable up to 260°C under thermal gravimetric anal. The ionic conductivities, investigated using dielec. relaxation spectroscopy, follow the Arrhenius temperature dependence with discontinuities and changes in slopes at the observed solid-solid phase transition temperature Dye-sensitized solar cells (DSSCs) fabricated by a whole solid-state electrolyte consisting of n-hexyl side-armed bis-imidazolium iodide (BII-6) show a 4.93% power conversion efficiency (η): a remarkable result for the solid-state electrolyte system compared to that obtained using an liquid electrolyte with 1-butyl-3-methylimidazolium iodide (η = 8.00%) as a reference composition1,2-Diiodoethane(cas: 624-73-7Safety of 1,2-Diiodoethane) was used in this study.

In 2016,Zhang, Wei; Tan, Yue Hua; Finch, James A. published 《Synthesis and characterization of alkyl, propoxy, ethoxy-based frothers》.Minerals Engineering published the findings.Safety of 1,2-Diiodoethane The information in the text is summarized as follows:

In this paper the authors describe the synthesis and characterization of a homologous series of linear polyglycol-based frothers comprising alkyl, propoxy (propylene oxide, PO), and ethoxy (ethylene oxide, EO) groups. The identities were confirmed by proton NMR spectroscopy and total organic carbon anal. Characterization used three parameters, bubble size, gas holdup and water overflow rate, measured in a bubble column. The results indicate that increasing number of PO groups led to significant decrease in bubble size, and increase in gas holdup and water overflow rate. Increasing the alkyl chain length, gave similar but less pronounced trends; the least effect was increasing the number of EO groups. Changing the relative position of the PO and EO group had a significant effect on all three parameters. To account for the effect of PO/EO position, a mechanism based on effect of structure on mol. packing at the air/water interface is proposed. In addition to this study using 1,2-Diiodoethane, there are many other studies that have used 1,2-Diiodoethane(cas: 624-73-7Safety of 1,2-Diiodoethane) was used in this study.
