In 2022,Zhu, Yu-Rong; Lin, Jin-Hong; Xiao, Ji-Chang published an article in Synlett. The title of the article was 《Triphenylphosphine/1,2-Diiodoethane-Promoted Formylation of Indoles with N,N -Dimethylformamide》.HPLC of Formula: 624-73-7 The author mentioned the following in the article:

A Ph3P/ICH2CH2I-promoted formylation of indoles with DMF under mild conditions was described. A Vilsmeier-type intermediate was readily formed from DMF promoted by the Ph3P/ICH2CH2I system. A one-step formylation process was applied to various electron-rich indoles, but a hydrolysis needs to be carried out as a second step in the case of electron-deficient indoles. Convenient operations make this protocol attractive. In the part of experimental materials, we found many familiar compounds, such as 1,2-Diiodoethane(cas: 624-73-7HPLC of Formula: 624-73-7)

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 Simmons–Smith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.HPLC of Formula: 624-73-7

Dalal, Arup; Babu, Srinivasarao Arulananda published their research in Synthesis in 2021. The article was titled 《Pd(II)-Catalyzed Directing-Group-Aided C-H Arylation and Alkylation of Pyrene Core: Synthesis of C1,C2- and C1,C10-Disubstituted Pyrene Motifs》.Related Products of 625-99-0 The article contains the following contents:

The application of the Pd(II)-catalyzed, directing-group-aided C-H arylation/alkylation tactics to functionalize the pyrene core, especially, the relatively inaccessible C2 I (R = H; R1 = quinolin-8-yl, 2-(methylsulfanyl)phenyl) and K-region C10 II (R2 = H) positions of the pyrene core and augmentation of the library of pyrene derivatives with C1,C2- I (R = Ph, 2,3-dihydro-1,4-benzodioxin-6-yl, thiophen-2-yl, etc.) and C1,C10-disubstituted pyrene II (R2 = 3,4-dimethylphenyl, 5-bromopyridin-2-yl, Ph, etc.) motifs was reported. The Pd(II)-catalyzed β-C-H arylation/alkylation of the C2-position of pyrene-1-carboxamide I possessing an 8-aminoquinoline directing group yielded various C1,C2-disubstituted pyrenes I. Similarly, the Pd(II)-catalyzed selective γ-C-H arylation/alkylation of the C10-position of N-(pyren-1-yl)picolinamide, possessing a picolinamide directing group, yielded various C1,C10-disubstituted pyrenes II. Examples of C(9)-H arylation of pyrene-1-carboxamide I (R1 = tert-butyl) and the removal of the directing group after the C-H arylation/alkylation reactions were also shown. The structures of representative pyrene derivatives were confirmed by the X-ray structure anal. Given the importance of the pyrene derivatives in various fields of chem. sciences, this report is a contribution towards augmentation of the library of pyrene derivatives with C1,C2- I and C1,C10-disubstituted pyrene amide motifs II.

In 2022,Adachi, Yohei; Kondo, Keisuke; Yin, Xiaodong; Jakle, Frieder; Ohshita, Joji published an article in Polymer. The title of the article was 《m-Phenylene linked macrocycle composed of electron-rich dithienogermole and electron-deficient tricoordinate boron units》.Electric Literature of C6H4BrI The author mentioned the following in the article:

Incorporation of non-conventional elements into π-conjugated systems is a powerful tool to control the electronic structures. In this work, electron-deficient tricoordinate boron units were combined with electron-rich dithienogermole units to provide an element-hybrid conjugated macrocycle with m-phenylene linkers. In contrast to the absorption spectra which were unaffected by solvent polarity, the element-hybrid macrocycle exhibited clear solvatochromism in the fluorescence spectra originating from the charge transfer (CT) transition between the dithienogermole and tricoordinate boron units. The addition of fluoride to the solution of the macrocycle resulted in the stoichiometric formation of tetracoordinate borate species. Interestingly, the fluorescence was intensified by the addition of fluoride, and the mechanism was confirmed by fluorescence spectroscopy and TD-DFT calculations In addition to this study using 1-Bromo-3-iodobenzene, there are many other studies that have used 1-Bromo-3-iodobenzene(cas: 591-18-4Electric Literature of C6H4BrI) was used in this study.

In 2018,Klein, Eugen; Heymann, Leonard; Hungria, Ana B.; Lesyuk, Rostyslav; Klinke, Christian published 《Colloidal lead iodide nanorings》.Nanoscale published the findings.Application of 624-73-7 The information in the text is summarized as follows:

Colloidal chem. of nanomaterials experienced a tremendous development in the last decades. In the course of the journey 0D nanoparticles, 1D nanowires, and 2D nanosheets have been synthesized. They have in common to possess a simple topol. We present a colloidal synthesis strategy for lead iodide nanorings, with a non-trivial topol. First, two-dimensional structures were synthesized in nonanoic acid as the sole solvent. Subsequently, they underwent an etching process in the presence of trioctylphosphine, which determines the size of the hole in the ring structure. We propose a mechanism for the formation of lead iodide nanosheets which also explains the etching of the two-dimensional structures starting from the inside, leading to nanorings. In addition, we demonstrate a possible application of the as-prepared nanorings in photodetectors. These devices are characterized by a fast response, high gain values, and a linear relation between photocurrent and incident light power intensity over a large range. The synthesis approach allows for inexpensive large-scale production of nanorings with tunable properties. In the part of experimental materials, we found many familiar compounds, such as 1,2-Diiodoethane(cas: 624-73-7Application of 624-73-7)
