16823-63-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16823-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,2 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16823-63:
(7*1)+(6*6)+(5*8)+(4*2)+(3*3)+(2*6)+(1*3)=115
115 % 10 = 5
So 16823-63-5 is a valid CAS Registry Number.

Aryl Radical-Mediated Alkenylation of Alkyl Halides

Chaambi, Ahmed,Kurtay, Gülbin,Abderrahim, Raoudha,Robert, Frédéric,Landais, Yannick

, (2019)

The free-radical alkenylation of a range of alkyl iodides with a vinyldisulfones has been carried out, leading to the desired vinylsulfones in moderate to good yields under mild conditions. The process is initiated by an aryl radical which abstracts the iodine atom from the alkyl iodide to form a C-centered radical intermediate, the addition of which onto the vinyldisulfone providing the final vinylsulfone. The aryl radical is generated in situ through a single-electron transfer from an electron donor-acceptor complex (EDA) formed between a diaryliodonium salt (Ph2I+ PF6?) and triethylamine.

Alkyl radical precursor and application thereof in establishing C-C bond

-

Paragraph 0145; 0146; 0148, (2018/09/14)

The invention provides a precursor for generating an alkyl radical based on the visible light induction and a novel method for generating the radical. The alkyl sulfenamide is used as the radical precursor to generate the alkyl radical by virtue of the C-S bond cracking accelerated by the visible light, and then the alkyl radical is applied to the chemical reaction for establishing a C-C bond. Thereaction system has the characteristic of high efficiency, and has important scientific significance and application value for researching the novel C-C bond formation reaction, organic synthesis, drug synthesis and the like. In general, the invention provides a novel general method having practical application value. The thioalcohol (thioether) with rich resources is converted to a tool for derivating the alkyl radical.

Schiff base complex of Mo supported on iron oxide magnetic nanoparticles (Fe3O4) as recoverable nanocatalyst for the selective oxidation of sulfides

Aghajani, Milad,Monadi, Niaz

, p. 963 - 975 (2017/03/11)

In this work, a new tridentate Schiff base dioxo-molybdenum(VI) complex immobilized on silica-coated magnetic nanoparticles (MoO25CML–Fe3O4@SiO2) has been synthesized and characterized using different techniques such as FTIR, TGA, AAS, ICP–AES, XRD, VSM, EDX and SEM analyses. The catalytic activity of synthesized complex was examined in the oxidation of various sulfides in the presence of H2O2 as cheap, green and eco-friendly oxidant. This catalytic system provides high conversion and selectivity toward either sulfoxides or sulfones under different conditions. Also, the nanocatalyst could be easily separated and regenerated from reaction media by external magnet and could be reused for ten times without significant loss of the activity and selectivity.
