The dehydroxytrifluoromethoxylation of alcs. promoted by a R3P/ICH2CH2I (R3P = Ph3P or Ph2PCH=CH2) system in DMF was reported. P-I halogen bonding drives the reaction of R3P with ICH2CH2I in DMF to generate iodophosphonium salt (R3P+I I-) and a Vilsmeier-Haack-type intermediate, both of which could effectively activate alcs., thus enabling a fast (15 min) trifluoromethoxylation reaction. A wide substrate scope and a high level of functional group tolerance were observed In the experiment, the researchers used many compounds, for example, 1,2-Diiodoethane(cas: 624-73-7Related Products of 624-73-7)

In 2022,Hu, Jing; Gao, Bo; Qi, Qi; Zuo, Zhuang; Yan, Kai; Hou, Shaocong; Zou, Dechun published an article in ACS Omega. The title of the article was 《Flexible and Conductive Polymer Threads for Efficient Fiber-Shaped Supercapacitors via Vapor Copolymerization》.Formula: C4H4INO2 The author mentioned the following in the article:

Flexible fiber electrodes are critical for high-performance fiber and wearable electronics. In this work, we presented a highly conductive all-polymer fiber electrode by vapor copolymerization of 2,5-dibromo-3,4-vinyldioxythiophene (DBEDOT) and 2,5-diiodo-3,4-vinyldioxythiophene (DIEDOT) monomers on commonly used polyester threads (PETs) at a temperature as low as 80°C. The poly(3,4-ethylenedioxythiophene) (PEDOT)-coated PET threads maintain excellent flexibility and show conductivity of 7.93 S cm-1, nearly four times higher than that reported previously via homopolymerization of DBEDOT monomer. A MnO2 active layer was embedded into the PEDOT double layers, and the flexible fiber composite electrode showed a high linear specific capacitance of 157 mF cm-1 and improved stability, retaining 86.5% capacitance after 5000 cycles. Fiber-shaped solid-state supercapacitors (FSSCs) based on the composite electrodes were assembled, and they displayed superior electrochem. performance. This work provides a new approach to realize high-performance and stable wearable electronics. The experimental part of the paper was very detailed, including the reaction process of 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Formula: C4H4INO2)

The synthetic utilities of acylgermanes are surprisingly rarely explored compared with their analogs. The survey of aroyltrimethylgermane as potent synthetic origins was studied. A variety of novel chem. transformations were realized, including using the acylgermane group as a directing group in Rh-catalyzed aromatic C-H alkenylation reaction and Ir-catalyzed aromatic C-H amidation reactions. Addnl., a general approach for acylgermanes preparation was established as well. The catalytic system proceeds effectively in the presence of Pd(OAc)2/BINOL-based monophosphite (L11) and allows for the straightforward access to a wide range of functionalized acylgermanes in high yields. In the experiment, the researchers used 1-Iodonaphthalene(cas: 90-14-2Recommanded Product: 1-Iodonaphthalene)

1-Iodonaphthalene(cas: 90-14-2) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom.

《Porous honeycomb-like NiSe2/red phosphorus heteroarchitectures for photocatalytic hydrogen production》 was written by Jia, Jia; Bai, Xue; Zhang, Qiqi; Hu, Xiaoyun; Liu, Enzhou; Fan, Jun. Reference of 1-Iodopyrrolidine-2,5-dione And the article was included in Nanoscale in 2020. The article conveys some information:

Heterojunction construction of semiconductors with a matched bandgap can not only help promote visible light absorption but also restrain photoexcited charge carrier recombination and optimize the separation efficiency. Herein, a novel porous honeycomb-like NiSe2/RP heterostructure is reported for the first time by in situ deposition of NiSe2 nanoparticles on the surface of red phosphorus (RP). The optimized binary NiSe2/RP composite showed superior photocatalytic H2 evolution activity (1968.8μmol g-1 h-1) from Na2S/Na2SO3 solution under solar light illumination, which was 2.32, 1.90, 1.59 and 1.21 times that of pristine RP, NiSe2, 5.3% FeS/RP and 8.1% NiS/RP, resp. Such a prominently improved photocatalytic performance could be ascribed to extended light absorption ability, massive reactive centers and lower interfacial transfer resistance, together with expedited charge separation, which arose from a successive two-electron/two-step reduction route. This study provides illuminating insights for the rational exploration and fabrication of potential photocatalytic systems with 0D/3D integrated nanoarchitecture and a multi-step electron transfer process for efficiently realizing solar energy capture and conversion.

Category: iodides-buliding-blocksIn 2020 ,《A pyranoxanthone as a potent antimitotic and sensitizer of cancer cells to low doses of paclitaxel》 appeared in Molecules. The author of the article were Franca, Fabio; Silva, Patricia M. A.; Soares, Jose X.; Henriques, Ana C.; Loureiro, Daniela R. P.; Azevedo, Carlos M. G.; Afonso, Carlos M. M.; Bousbaa, Hassan. The article conveys some information:

Microtubule-targeting agents (MTAs) remain a gold standard for the treatment of several cancer types. By interfering with microtubules dynamic, MTAs induce a mitotic arrest followed by cell death. This antimitotic activity of MTAs is dependent on the spindle assembly checkpoint (SAC), which monitors the integrity of the mitotic spindle and proper chromosome attachments to microtubules in order to ensure accurate chromosome segregation and timely anaphase onset. However, the cytotoxic activity of MTAs is restrained by drug resistance and/or toxicities, and had motivated the search for new compounds and/or alternative therapeutic strategies. Here, we describe the synthesis and mechanism of action of the xanthone derivative pyranoxanthone 2 that exhibits a potent anti-growth activity against cancer cells. We found that cancer cells treated with the pyranoxanthone 2 exhibited persistent defects in chromosome congression during mitosis that were not corrected over time, which induced a prolonged SAC-dependent mitotic arrest followed by massive apoptosis. Importantly, pyranoxanthone 2 was able to potentiate apoptosis of cancer cells treated with nanomolar concentrations of paclitaxel. Our data identified the potential of the pyranoxanthone 2 as a new potent antimitotic with promising antitumor potential, either alone or in combination regimens.2-Iodobenzoic acid(cas: 88-67-5Category: iodides-buliding-blocks) was used in this study.
