Iodination of deactivated aromatics with N-iodosuccinimide in trifluoromethanesulfonic acid (NIS-CF3SO3H) via in situ generated superelectrophilic iodine(I) trifluoromethanesulfonate>, Category: iodides-buliding-blocks, the main research area is iodination aromatic iodosuccinimide trifluoromethanesulfonic acid.

Deactivated aromatic compounds are readily iodinated by N-iodosuccinimide in trifluoromethanesulfonic acid (triflic acid) in good yields. Thus, PhNO2 was treated with NIS-CF3SO3H to give 3-iodonitrobenzene in 86% yield. The novel iodination is suggested to involve in situ generated and protosolvated iodine(I) trifluoromethanesulfonate.

Lu, Xiaofeng; Sun, Jibin; Liu, Yu; Shao, Jiafeng; Ma, Longfei; Zhang, Shangxi; Zhao, Jinlian; Shao, Yongliang; Zhang, Hao-Li; Wang, Zhaohui; Shao, Xiangfeng published the artcile< Decorating Tetrathiafulvalene (TTF) with Fluorinated Phenyls through Sulfur Bridges: Facile Synthesis, Properties, and Aggregation through Fluorine Interactions>, Quality Control of 2265-92-1, the main research area is fluorinated phenyl TTF derivative preparation aggregation CV UVVis; C-S coupling; TTF derivatives; electrochemistry; fluorine interactions; photochemistry.

Tetrathiafulvalene derivatives (TTF1-TTF9) bearing fluorinated Ph groups attached through the sulfur bridges have been synthesized by employing a copper-mediated C-S coupling reaction of C6H5-xFxI (x = 1, 2, 5) and a zinc-thiolate complex, (TBA)2[Zn(DMIT)2] (TBA = tetra-Bu ammonium, DMIT = 1,3-dithiole-2-thione-4,5-dithiolate), as the key step. Particularly, the selective synthesis of C6F5-substituted (TTF8) and C6F4-fused (TTF9) TTFs from C6F5I is disclosed. The physicochem. properties and crystal structures of these TTFs are fully investigated by UV/Vis absorption spectra, cyclic voltammetry, MO calculation, and single-crystal X-ray diffraction. The exchange of hydrogen vs. fluorine on the peripheral Ph groups show a notable influence on both the electronic and crystallog. natures of the resulting TTFs: (1) lowering both the HOMO and the LUMO energy levels, (2) modulating the electrochem. properties by regioselective and/or the degree of fluorination, (3) enhancing the driving forces of stacking by multiple fluorine interactions (F···S, C-F···π/πF, C-F···F-C, and C-F···H). This work indicates that the decoration with fluorinated phenyls holds promise to produce functional TTFs with novel electronic and aggregation features.

Li, Xujun;Li, Jia;Wang, Xiaoshuang;Wu, Lingang;Wang, Yanlan;Maestri, Giovanni;Malacria, Max;Liu, Xiang research published 《 Photoelectric properties of aromatic triangular tri-palladium complexes and their catalytic applications in the Suzuki-Miyaura coupling reaction》, the research content is summarized as follows. The photoelec. properties and catalytic activities of substituted triphenylphosphine and sulfur/selenium ligand supported aromatic triangular tri-palladium complexes 1–4, abbreviated as [Pd₃]⁺, were studied. The cyclic voltammogram of [Pd₃]⁺ in CH₃CN-Bu₄NPF₆ showed a single quasi-reversible wave which was consistent with their robust property and provided preliminary proof for their electron transfer processes in catalysis. With excitation at 267 nm, [Pd₃]⁺ exhibited strong ratiometric fluorescence at 550 and 780 nm at a temperature gradient from 77 K to 287 K. These peculiar triangular tri-palladium complexes showed excellent catalytic activities and exclusive reactivity with aryl iodides over the other halogenated aromatics in the Suzuki-Miyaura coupling reaction. The electronic and steric hindrance effects of substituents on the aryl iodides and aryl boronic acids including heteroaromatics like pyridine, pyrazine and thiophenes were explored and most substrates achieved up to 99% of yields. (2-[1,1′-Biphenyl]-2-ylbenzothiazole) which was analogous to the selective cyclooxygenase-2 (COX-2) inhibitors was also synthesized with the authors’ tri-palladium catalyst and gave good isolated yield (94%). The study of the catalytic process revealed that the mechanism of the reaction may involve the replacement of the sulfur ligand on [Pd₃]⁺ by iodine from aryl iodides, which was beneficial for the matching of C-I bond energy.

Highly efficient photoinduced Ni-catalyzed method for the C-heteroatom cross-coupling of aryl halides was reported. The reaction proceeded smoothly in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) under visible light irradiation and was distinct from that mediated by photoredox/nickel dual catalysis, requiring no external photosensitizers. A diverse range of nucleophiles, including amines, amides, sulfonamides, carboxylic acids, alcs., thiophenol, phosphite and sodium sulfinate, were successfully coupled with electronically diverse aryl halides, presenting a universal approach for different C-heteroatom coupling reactions.

Li, Mingle;Gebremedhin, Kalayou Hiluf;Ma, Dandan;Pu, Zhongji;Xiong, Tao;Xu, Yunjie;Kim, Jong Seung;Peng, Xiaojun research published 《 Conditionally Activatable Photoredox Catalysis in Living Systems》, the research content is summarized as follows. The transformational effect of photoredox catalytic chemistries has inspired new opportunities, enabling us to interrogate nature in ways that are not possible otherwise and to unveil new biotechnologies in therapy and diagnosis. However, the deployment of artificial photoredox catalysis in living systems remains challenging, mired by the off-target risk and safety concerns of photocatalyst toxicity. Here, we present an appealing approach, namely conditionally activatable photoredox catalysis (ConAPC), and as a proof of concept design the first ConAPC architecture (Se-NO₂) based upon classic self-immolative chem., in which the inherent photocatalytic properties can be temporarily caged while the species becomes active only at the tumor sites via sensing to specific biomarkers. Such a masking strategy allows a spatial-temporal control of photoresponsivity in vitro and in vivo. In particular, for ConAPC design, a new biol. benign metal-free photocatalyst (Se-NH₂), which is able to initiate NIR photoredox catalysis to manipulate the cellular electron pool in an O₂-independent mechanism of action, is identified. With this unique strategy, potent tumor-specific targeting photocatalytic eradication (TGI: 95%) is obtained in a mouse model. Impressively, favorable features such as high-resolution tumor recognition (SBR: 33.6) and excellent biocompatibility and safety are also achieved. This work therefore offers a new possibility for chemists to leverage artificial photocatalytic reactions toward the development of facile and intelligent photocatalytic theranostics.
