Herein, a mild, rapid, straightforward method for visible-light-mediated sulfonamide ethylation to afford a diverse array of compounds with C(sp3)-sulfonamide skeletons RS(O)2N(R1)R2 (R = 4-phenylbutyl, 3,3-dimethylbutyl, 2-cyclobutylethyl, 4-(pyridin-2-yl)butyl, etc.; R1 = H, Ph, 2-oxooxolan-3-yl, benzyl, etc.; R2 = H, Me, phenyl) was reported. The method relies on inexpensive, abundant, com. available primary, secondary, and tertiary alkyl carboxylic acids I (R3 = 2-phenylethyl, 2,2-diphenylethyl, 2-(pyridin-3-yl)ethyl, pentyl, etc.) and alkyl iodides R4I (R4 = 2-cyclohexylethyl, pentyl, 4-(trimethylsilyl)butyl, hept-6-yn-1-yl, etc.) as substrates.

Pei, Xiaoyan; Xiang, Deng; Luo, Zhengxiu; Lei, Fukun; Guo, Zhanglong; Liu, Dong; Zhao, Zhigang; Ran, Maofei; Dai, Tao published an article in 2021. The article was titled 《Catalytic performance of palladium nanoparticles encapsulated within nitrogen-doped carbon during Heck reaction》, and you may find the article in Journal of Catalysis.Application In Synthesis of 1-Bromo-4-iodobenzene The information in the text is summarized as follows:

The Confinement effect is an effective strategy for enhancing the performance of catalysts during various reactions. We developed a strategy to encapsulating Palladium nanoparticles with a dopamine-derived N-doped multilayer carbon shell to catalyze the Heck reaction between iodobenzene and carbon-carbon double-bond compounds (styrene and Me acrylate). The catalytic performances of Pd nanoparticles encapsulated within a N-doped carbon layer (Pd@N-C) and those attached to the external surface of such a layer (Pd/N-C) were evaluated and compared. Pd@N-C exhibited a lower reaction activation energy (78 kJ/mol) than that of Pd/N-C (106 kJ/mol). Thus, the activity of Pd@N-C during the Heck reaction between iodobenzene and Me acrylate was approx. 20 times higher than that of Pd/N-C-200. The results of thermal filtration and recycling tests indicated that Pd@N-C showed a lower degree of leaching than that of Pd/N-C-200 owing to the spatial restriction effect of the cavity in the case of the former. Hence, the superior catalytic performance of Pd@N-C can be ascribed to the confinement of the Pd nanoparticles within the N-doped carbon layer. Finally, we useCinnamatesd these catalysts to synthesize a range of para-substituted iodobenzene derivatives, thus demonstrating the potential of Pd-encapsulating catalysts for use in the Heck reaction on the tech. scale. The experimental part of the paper was very detailed, including the reaction process of 1-Bromo-4-iodobenzene(cas: 589-87-7Application In Synthesis of 1-Bromo-4-iodobenzene)

Synthetic Route of C5H5IN2OOn September 30, 2013 ,《Methylenepyran based dipolar and quadrupolar dyes: synthesis, electrochemical and photochemical properties》 was published in Tetrahedron. The article was written by Gauthier, Sebastien; Vologdin, Nikolay; Achelle, Sylvain; Barsella, Alberto; Caro, Bertrand; Robin-le Guen, Francoise. The article contains the following contents:

This paper presents the synthesis of a series of push-pull and quadrupolar π-conjugated structures incorporating pro-aromatic methylenepyran electron-donor groups and various electron-attracting groups. Some of the methylenepyran derivatives were oxidized by I2 to give, after reduction by Na2S2O3, bismethylenepyran compounds via successive steps. The electrochem. redox properties of methylenepyrans 5-9 and extended bismethylenepyrans 10, 14, and 15 determined by cyclic voltammetry indicate the formation of redox bistable systems with high bi-stability. Oxidation of the dimers obtained from 5 to 9 was also described. All compounds are colored and slightly fluorescent (except some bismethylenepyran derivatives). Some compound second-order nonlinear optical properties were investigated, and large pos. values of μβ were obtained. A pos. dimer effect was also observed for bispyran derivatives In the experimental materials used by the author, we found 4-Iodo-6-methoxypyrimidine(cas: 161489-05-0Synthetic Route of C5H5IN2O)

4-Iodo-6-methoxypyrimidine(cas: 161489-05-0) 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. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.Synthetic Route of C5H5IN2O

COA of Formula: C5H4INIn 2022 ,《Construction of emissive ruthenium(II) metallacycle over 1000 nm wavelength for in vivo biomedical applications》 was published in Nature Communications. The article was written by Xu, Yuling; Li, Chonglu; Lu, Shuai; Wang, Zhizheng; Liu, Shuang; Yu, Xiujun; Li, Xiaopeng; Sun, Yao. The article contains the following contents:

Although Ru(II)-based agents are expected to be promising candidates for substituting Pt-drug, their in vivo biomedical applications are still limited by the short excitation/emission wavelengths and unsatisfactory therapeutic efficiency. Herein, we rationally design a Ru(II) metallacycle with excitation at 808 nm and emission over 1000 nm, namely Ru1085, which holds deep optical penetration (up to 6 mm) and enhanced chemo-phototherapy activity. In vitro studies indicate that Ru1085 exhibits prominent cell uptake and desirable anticancer capability against various cancer cell lines, especially for cisplatin-resistant A549 cells. Further studies reveal Ru1085 induces mitochondria-mediated apoptosis along with S and G2/M phase cell cycle arrest. Finally, Ru1085 shows precise NIR-II fluorescence imaging guided and long-term monitored chemo-phototherapy against A549 tumor with minimal side effects. We envision that the design of long-wavelength emissive metallacycle will offer emerging opportunities of metal-based agents for in vivo biomedical applications.
