Check Digit Verification of cas no

The CAS Registry Mumber 104-95-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104-95:
(5*1)+(4*0)+(3*4)+(2*9)+(1*5)=40
40 % 10 = 0
So 104-95-0 is a valid CAS Registry Number.

A mild protocol for the deoxygenation of α-hydrogen-containing sulfoxides to the corresponding sulfides

Bhatia, Gurpreet S.,Graczyk, Piotr P.

, p. 5193 - 5195 (2004)

A mild method for the deoxygenation of α-hydrogen-containing sulfoxides to sulfides is reported. This synthetically useful and operationally simple protocol derives mechanistically from the Swern oxidation methodology.

Reduction of CO2 with NaBH4/I2 for the Conversion of Thiophenols to Aryl Methyl Sulfides

Zhang, Bo,Fan, Zhengning,Guo, Zhiqiang,Xi, Chanjuan

, p. 8661 - 8667 (2019)

We report a tandem reaction to realize reduction of carbon dioxide with thiophenols to generate aryl methyl sulfides under the NaBH4/I2 system with 18-crown-6 as the solvent. Thiophenols bearing electron-donating and electron-withdrawing groups are feasible in this reaction. Controlled experiment results indicate that 18-crown-6 plays a critical role in six-electron reduction of carbon dioxide.

Chemoenzymatic Deracemization of Chiral Sulfoxides

Nosek, Vladimír,Mí?ek, Ji?í

, p. 9849 - 9852 (2018)

The highly enantioselective enzyme methionine sulfoxide reductase A was combined with an oxaziridine-type oxidant in a biphasic setup for the deracemization of chiral sulfoxides. Remarkably, high ee values were observed with a wide range of substrates, thus providing a practical route for the synthesis of enantiomerically pure sulfoxides.

In situ acidic carbon dioxide/ethanol system for selective oxybromination of aromatic ethers catalyzed by copper chloride

Liu, An-Hua,He, Liang-Nian,Hua, Fang,Yang, Zhen-Zhen,Huang, Cheng-Bin,Yu, Bing,Li, Bin

, p. 3187 - 3195 (2011)

An environmentally benign carbon dioxide/ethanol reversible acidic system was developed for the copper(II)-catalyzed regioselective oxybromination of aromatic ethers without the need of any conventional acid additive and organic solvent. Good to excellent yields together with very good regioselectivity were achieved when easily available cupric chloride dihydrate was used as catalyst and lithium bromide as the cheap and easy-to-handle bromine source under supercritical carbon dioxide conditions. Notably, the catalytic system worked well for a wide range of aromatic ethers including sulfides, resulting in the formation of the mono-brominated products in high yields and exclusive regioselectivity. The alkylcarbonic acid in situ formed from ethanol and carbon dioxide is assumed to play the crucial role in the Braonsted acid-promoted reaction, which could probably act as the proton donator, and was studied employing in situ FT-IR technique under carbon dioxide pressure by monitoring the vibration shift of the hydroxy group of ethanol. Given with excellent bromine atom efficiency as well as no need of neutralization in waste disposal, this approach thus represents a greener pathway for the aerobic bromination of aromatic ethers. A possible catalytic cycle for the in situ alkylcarbonic acid-assisted oxybomination and the effect of supercritical carbon dioxide, i.e., activation of alcohol and enhancement of mass transfer are also discussed.

A practical and chemoselective Mo-catalysed sulfoxide reduction protocol using a 3-mercaptopropyl-functionalized silica gel (MPS)

García, Nuria,Fernández-Rodríguez, Manuel A.,García-García, Patricia,Pedrosa, María R.,Arnáiz, Francisco J.,Sanz, Roberto

, p. 27083 - 27086 (2016)

A convenient sulfoxide deoxygenation procedure using a mercaptopropyl-functionalized silica gel as the reducing agent is described. This new protocol based on a heterogeneous reagent displays broad scope and tolerance to reducible functional groups and, from an experimental point of view, enhances previous methods by simplifying the isolation of the sulfide to a simple filtration.

Efficient hydrodeoxygenation of sulfoxides into sulfides under mild conditions using heterogeneous cobalt-molybdenum catalysts

Yao, Kaiyue,Yuan, Ziliang,Jin, Shiwei,Chi, Quan,Liu, Bing,Huang, Renjie,Zhang, Zehui

, p. 39 - 43 (2020)

Nitrogen-doped carbon-supported cobalt-molybdenum bimetallic catalysts (abbreviated as Co-Mo/NC) are active for the hydrodeoxygenation of sulfoxides to sulfides under mild conditions (25-80 °C and 10 bar H2), which represents the first example of the use of heterogeneous non-noble metal catalysts for this transformation. MoO3 with Lewis acid sites assists the hydrodeoxygenation of sulfoxides into sulfides by hydrogen over cobalt nanoparticles.

Nickel phosphide nanoalloy catalyst for the selective deoxygenation of sulfoxides to sulfides under ambient H2pressure

Fujita, Shu,Mitsudome, Takato,Mizugaki, Tomoo,Yamaguchi, Sho,Yamasaki, Jun,Yamazoe, Seiji

, p. 8827 - 8833 (2020)

Exploring novel catalysis by less common, metal-non-metal nanoalloys is of great interest in organic synthesis. We herein report a titanium-dioxide-supported nickel phosphide nanoalloy (nano-Ni2P/TiO2) that exhibits high catalytic activity for the deoxygenation of sulfoxides. nano-Ni2P/TiO2 deoxygenated various sulfoxides to sulfides under 1 bar of H2, representing the first non-noble metal catalyst for sulfoxide deoxygenation under ambient H2 pressure. Spectroscopic analyses revealed that this high activity is due to cooperative catalysis by nano-Ni2P and TiO2. This journal is

supporting information, (2022/01/19)

Trihalide salts were found to efficiently promote photochemical dediazotizing halogenations of diazonium salts. In contrast to classical Sandmeyer reactions, no metal catalysts are required to achieve high yields and outstanding selectivities for halogena

Synthesis of Aryl Methyl Sulfides from Arysulfonyl Chlorides with Dimethyl Carbonate as the Solvent and C1 Source

Miao, Ren-Guan,Qi, Xinxin,Wu, Xiao-Feng

supporting information, p. 5219 - 5221 (2021/10/19)

A new procedure for the synthesis of aryl methyl sulfides from dimethyl carbonate (DMC) and arylsulfonyl chlorides has been achieved. In this strategy, DMC plays a dual role as both, C1 building block and green solvent. Arylsulfonyl chlorides served as the sulfur precursors, and a variety of aryl methyl sulfides were obtained in moderate to excellent yields with good functional group tolerance. Additionally, alkylsulfonyl chloride and dibenzyl carbonate are proven to be suitable substrates as well.
