Check Digit Verification of cas no

The CAS Registry Mumber 709-21-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 709-21:
(5*7)+(4*0)+(3*9)+(2*2)+(1*1)=67
67 % 10 = 7
So 709-21-7 is a valid CAS Registry Number.

Circumventing Intrinsic Metal Reactivity: Radical Generation with Redox-Active Ligands

Jacquet, Jérémy,Cheaib, Khaled,Ren, Yufeng,Vezin, Hervé,Orio, Maylis,Blanchard, Sébastien,Fensterbank, Louis,Desage-El Murr, Marine

, p. 15030 - 15034 (2017)

Nickel complexes have gained sustained attention as efficient catalysts in cross-coupling reactions and co-catalysts in dual systems due to their ability to react with radical species. Central to this reactivity is nickel's propensity to shuttle through several accessible redox states from Ni0 to NiIV. Here, we report the catalytic generation of trifluoromethyl radicals from a nickel complex bearing redox-active iminosemiquinone ligands. This unprecedented reactivity is enabled through ligand-based oxidation performing electron transfer to an electrophilic CF3+ source while the nickel oxidation state is preserved. Additionally, extension of this reactivity to a copper complex bearing a single redox equivalent is reported, thus providing a unified reactivity scheme. These results open new pathways in radical chemistry with redox-active ligands.

A multicomponent cascade reaction is described that provides concise access to the trifluoroethyl isoquinolines using a Rh(III)-Cu(II) bimetallic system and readily available Togni's reagent. The system tolerates various vinyl azides and internal alkynes. Experimental results suggest that Togni's reagent might act as a CF3 radical supplier.

Rational Design and Development of Low-Price, Scalable, Shelf-Stable and Broadly Applicable Electrophilic Sulfonium Ylide-Based Trifluoromethylating Reagents

Ge, Hangming,Ling, Yijing,Liu, Yafei,Lu, Long,Shen, Qilong

, p. 1667 - 1682 (2021/05/28)

The development of two highly reactive electrophilic trifluoromethylating reagents (trifluoromethyl)(4-nitrophenyl)bis(carbomethoxy)methylide (1g) and (trifluoromethyl)(3-chlorophenyl)bis(carbomethoxy)methylide (1j) through structure-activity study was described. Under mild conditions, reagent 1g reacted with β-ketoesters and silyl enol ethers to give α-trifluoromethylated-β-ketoesters or α-trifluoromethylated ketones in high yields. In addition, reagent 1g could serve as a trifluoromethyl radical for a variety of trifluoromethylative transformations under visible light irradiation, including radical trifluoromethylation of electron-rich indoles and pyrroles and sodium aryl sulfinates as well as trifluoromethylative difunctionalization with styrene derivatives. On the other hand, as a complimentary, under reductive coupling conditions, reagent 1j reacted with a variety of (hetero)aryl iodides for the formation of trifluoromethylated (hetero)arenes.

A General Organocatalytic System for Electron Donor-Acceptor Complex Photoactivation and Its Use in Radical Processes

De Pedro Beato, Eduardo,Melchiorre, Paolo,Spinnato, Davide,Zhou, Wei

supporting information, p. 12304 - 12314 (2021/08/20)

We report herein a modular class of organic catalysts that, acting as donors, can readily form photoactive electron donor-acceptor (EDA) complexes with a variety of radical precursors. Excitation with visible light generates open-shell intermediates under mild conditions, including nonstabilized carbon radicals and nitrogen-centered radicals. The modular nature of the commercially available xanthogenate and dithiocarbamate anion organocatalysts offers a versatile EDA complex catalytic platform for developing mechanistically distinct radical reactions, encompassing redox-neutral and net-reductive processes. Mechanistic investigations, by means of quantum yield determination, established that a closed catalytic cycle is operational for all of the developed radical processes, highlighting the ability of the organic catalysts to turn over and iteratively drive every catalytic cycle. We also demonstrate how the catalysts' stability and the method's high functional group tolerance could be advantageous for the direct radical functionalization of abundant functional groups, including aliphatic carboxylic acids and amines, and for applications in the late-stage elaboration of biorelevant compounds and enantioselective radical catalysis.

Vil’, Vera A.,Merkulova, Valentina M.,Ilovaisky, Alexey I.,Paveliev, Stanislav A.,Nikishin, Gennady I.,Terent’ev, Alexander O.

supporting information, p. 5107 - 5112 (2021/06/30)

The electrochemical synthesis of fluorinated ketones from enol acetates and RfSO2Na in an undivided cell under constant current conditions was developed. The electrosynthesis proceeded via perfluoroalkyl radical generation from sodium perfluoroalkyl sulfinate followed by addition to the enol acetate and transformation of the resulting C radical to a fluorinated ketone. The method is applicable to a wide range of enol acetates and results in the desired products in yields of 20 to 85%.

Scissoring Enaminone C=C Double Bond by Free Radical Process for the Synthesis of α-Trifluoromethyl Ketones with CF3SO2Na

Gan, Lu,Yu, Qing,Liu, Yunyun,Wan, Jie-Ping

, p. 1231 - 1237 (2020/12/21)

The C=C double bond cleavage on tertiary enaminones, enabling the formation of a new C-CF3 bond, has been realized as a practical method for the synthesis of α-trifluoromethyl ketones with only the promotion of TBHP and ambient heating. Control experiments support that the reactions proceed via a featured free radical process. The deuterium labeling experiment employing D2O indicates that water participated in the product formation by donating the hydrogen atom for the newly generated α-C-H bond in the product.
