BiI3 nanosheet dispersions were prepared by ultrasound-mediated exfoliation of BiI3 in the green solvents Me salicylate, triacetin, di-Et phthalate, Et benzoate, or in mixtures of the solvents. BiI3 nanosheets were formed in up to 30% yields and as dispersions containing up to 1.56 mg/mL of BiI3; the thickness of the BiI3 nanosheets is 5-10 nm and their lateral dimensions are around 1μm. Solvent-cosolvent interactions in the mixed solvents are a critical factor in the liquid-phase exfoliation. The BiI3 nanosheets were used as a catalyst for the Suzuki coupling of aryl iodides with phenylboronic acid mediated by TMEDA and KOH in THF to yield 4-substituted biphenyls in 75-91% yields.

《Self-assembly of coordination polyhedra with highly entangled faces induced by metal-acetylene interactions》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Domoto, Yuya; Abe, Masahiro; Kikuchi, Takashi; Fujita, Makoto. HPLC of Formula: 591-18-4 The article mentions the following:

The self-assembly of nanostructures is dominated by a limited number of strong coordination elements. Herein, we show that metal-acetylene π-coordination of a tripodal ligand (L) with acetylene spacers gave an M3L2 double-propeller motif (M=CuI or AgI), which dimerized into an M6L4 interlocked cage (M=CuI). Higher (M3L2)n oligomers were also selectively obtained: an M12L8 truncated tetrahedron (M=CuI) and an M18L12 truncated trigonal prism (M=AgI), both of which contain the same double-propeller motif. The higher oligomers exhibit multiply entangled facial structures that are classified as a trefoil knot and a Solomon link. The inner cavities of the structures encapsulate counter anions, revealing a potential new strategy towards the synthesis of functional hollow structures that is powered by mol. entanglements. The experimental process involved the reaction of 1-Bromo-3-iodobenzene(cas: 591-18-4HPLC of Formula: 591-18-4)

《meta-Selective C-H Arylation of Fluoroarenes and Simple Arenes》 was written by Liu, Luo-Yan; Qiao, Jennifer X.; Yeung, Kap-Sun; Ewing, William R.; Yu, Jin-Quan. Name: 1-Chloro-3-iodobenzene And the article was included in Angewandte Chemie, International Edition in 2020. The article conveys some information:

Fluorine is known to promote ortho-C-H metalation. Based upon this reactivity, we employed an activated norbornene that traps the ortho-palladation intermediate and is then relayed to the meta position, leading to meta-selective C-H arylation of fluoroarenes. Deuterium experiment suggests that this meta-arylation is initiated by ortho C-H activation and the catalytic cycle is terminated by C-2 protonation. A dual-ligand system is crucial for the observed high reactivity and site selectivity. Applying this approach to simple benzene or other arenes also affords arylation products with good yield and site selectivity. In the experiment, the researchers used many compounds, for example, 1-Chloro-3-iodobenzene(cas: 625-99-0Name: 1-Chloro-3-iodobenzene)

1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Name: 1-Chloro-3-iodobenzene Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.

Li, Haoyu; Tang, Xinxin; Pang, Jia Hao; Wu, Xiangyang; Yeow, Edwin K. L.; Wu, Jie; Chiba, Shunsuke published their research in Journal of the American Chemical Society in 2021. The article was titled 《Polysulfide anions as visible light photoredox catalysts for aryl cross-couplings》.Electric Literature of C10H18INO2 The article contains the following contents:

Polysulfide anions are endowed with unique redox properties, attracting considerable attentions for their applications in alkali metals-sulfur batteries. However, the employment of these anionic species in redox catalysis for small mol. synthesis remains underdeveloped due to their moderate-poor electrochem. potential in the ground state, whereas some of them are characterized by photoabsorptions in visible spectral regions. Herein, we disclose the use of polysulfide anions as visible light photoredox catalysts for aryl cross-coupling reactions. The reaction design enables single-electron reduction of aryl halides upon the photoexcitation of tetrasulfide dianions (S42-). The resulting aryl radicals are engaged in (hetero)biaryl cross-coupling, borylation, and hydrogenation in a redox catalytic regime involving S4• -/S42- and S3• -/S32- redox couples. In the experiment, the researchers used many compounds, for example, tert-Butyl 4-iodopiperidine-1-carboxylate(cas: 301673-14-3Electric Literature of C10H18INO2)

tert-Butyl 4-iodopiperidine-1-carboxylate(cas: 301673-14-3) is one of organic iodides. Organic iodides are used in veterinary products (Organic Iodide Powder) as a nutritional source of iodine.

El Nemr, Ahmed; Eleryan, Ahmed; Mashaly, Mohammad; Khaled, Azza published their research in Polymer Bulletin (Heidelberg, Germany) in 2021. The article was titled 《Comparative study of synthesis of cellulose propionate from different sources using NIS as a new catalyst》.Name: 1-Iodopyrrolidine-2,5-dione The article contains the following contents:

Propylation of cellulose from different sources with propionic anhydride using N-iodosuccinimide (NIS) under solvent-free condition was tested. It was done in the presence of NIS as a new catalyst for propylation using three different amounts of catalyst under mild reaction conditions. The degree of substitution by propionate was exptl. calculated and confirmed by FTIR and 1H NMR analyses. The propylation yields varied from 71.54 to 88.37% with the degree of substitution (DS) ranged from 1.32 to 2.80 for com. cotton cellulose, 1.76-3.00 for rice husk cellulose, and 1.60-3.0 for wheat straw cellulose. The DS were easily controlled by changing the reaction duration (2-6 h) and the amount of the NIS catalyst (50, 75, and 100 mg for each 1.0 g of cellulose) in 25 mL of propionic anhydride. Prolonging the reaction’s duration has no favorable effect on the propylation process and led to decrease in the cellulose propionate (CP). Also, increasing the amount of NIS catalyst results in decrease the DS and CP yield. NIS was recognized as a novel and more successful catalyst for propylation of the hydroxyl groups of cellulose from different sources in high degree of substitution. In the experimental materials used by the author, we found 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Name: 1-Iodopyrrolidine-2,5-dione)

Huang, Weibo; Tong, Zhouyu; Bi, Yuxin; Ma, Mingliang; Liao, Zijian; Wu, Guanglei; Ma, Yong; Guo, Siyu; Jiang, Xiaoyu; Liu, Xueping published an article in 2021. The article was titled 《Synthesis and microwave absorption properties of coralloid core-shell structure NiS/Ni3S4@PPy@MoS2 nanowires》, and you may find the article in Journal of Colloid and Interface Science.Quality Control of 1-Iodopyrrolidine-2,5-dione The information in the text is summarized as follows:

Herein, coralloid core-shell structure NiS/Ni3S4@PPy@MoS2 nanowires were elaborately designed and successfully synthesized through a three-step route to obtain exceptional microwave absorption (MA) properties. Ni nanowires were first fabricated, and then used as the substrate to be coated with a layer of PPy. Ni chalcogenides were obtained by using Ni nanowire as sacrificial templates while growing MoS2 nanorods by hydrothermal method. Both the one-dimensional (1D) core-shell structure and the coralloid surface generated by MoS2 nanorods were beneficial for the attenuation of microwaves. After investigating the electromagnetic properties of different loading content absorbers (30 weight%, 40 weight% and 50 weight%), it is found that the 50 weight% loading absorber has the optimal MA performance. The min. reflection loss (RLmin) value can reach -51.29 dB at 10.1 GHz with a thickness of 2.29 mm, and the corresponding effective absorption bandwidth (EAB, RL < -10 dB) can be up to 3.24 GHz. This research provides a reference for exploiting novel high-efficient 1D absorbers in the field of MA.
