274928-75-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 274928-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,4,9,2 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 274928-75:
(8*2)+(7*7)+(6*4)+(5*9)+(4*2)+(3*8)+(2*7)+(1*5)=185
185 % 10 = 5
So 274928-75-5 is a valid CAS Registry Number.

A highly efficient reusable homogeneous copper catalyst for the selective aerobic oxygenation sulfides to sulfoxides

Ren, Cheng,Fang, Runxing,Yu, Xiaochun,Wang, Shun

, p. 982 - 986 (2018)

Readily available copper showed efficient activity and great selectivity for the homogeneous catalysis of oxidation of sulfides to sulfoxides using molecular oxygen as the oxidant. The reaction proceeds under mild conditions in the presence of a catalytic amount of TEMPO. Importantly, the catalysts could be conveniently recovered and reused. And this methodology was proved to be applicable for the transformation of various aromatic and aliphatic sulfides into the corresponding sulfoxides with high conversion and high selectivity.

Two-dimensional crystalline covalent triazine frameworksviadual modulator control for efficient photocatalytic oxidation of sulfides

Jin, Shangbin,Lang, Xianjun,Li, Xia,Tan, Bien,Wang, Xuepeng,Zhan, Zhen,Zhang, Siquan

, p. 16405 - 16410 (2021)

Two-dimensional crystalline covalent triazine frameworks (2D-CTFs) are emerging 2D materials with the characteristics of fully annulated conjugated structures and aromatic nitrogen-rich skeletons. Due to the difficulty in the control of the polymerization

Green catalysis for the selective oxidation of sulfides with high turnover numbers in water at room temperature

Zhao, Wei,Yang, Chunxia,Sun, Hongxian,Cheng, Zhiguo,Chang, Tao

, p. 19349 - 19352 (2018)

A hybrid catalyst based on monoprotonated divanadium-substituted phosphotungstate ([γ-HPV2W10O40]4?) was synthesized and used for the selective oxidation of sulfides. The catalytic system was carried out in water with hydrogen peroxide at room temperature. Unprecedented turnover numbers (TONs) for all substrates were obtained, which are much higher than previous reports.

Air atmospheric photocatalytic oxidation by ultrathin C,N-TiO2nanosheets

Cheng, Xiuyan,Zhang, Jianling,Liu, Lifei,Zheng, Lirong,Zhang, Fanyu,Duan, Ran,Sha, Yufei,Su, Zhuizhui,Xie, Fei

supporting information, p. 1165 - 1170 (2021/02/26)

Herein, we demonstrate the highly efficient photocatalytic sulfide oxidation reaction under mild conditions,i.e.in air, at room temperature and in the absence of a sacrificial reagent, co-catalyst or redox mediator, by using ultrathin C,N-TiO2nanosheets as a photocatalyst.

Sulfoxide and Sulfone Synthesis via Electrochemical Oxidation of Sulfides

Lee, Sunwoo,Park, Jin Kyu

, p. 13790 - 13799 (2021/10/12)

The oxidation of diaryl sulfides and aryl alkyl sulfides to the corresponding sulfoxides and sulfones under electrochemical conditions is reported. Sulfoxides are selectively obtained in good yield under a constant current of 5 mA for 10 h in DMF, while sulfones are formed as the major product under a constant current of 10 or 20 mA for 10 h in MeOH. The oxygen of both the sulfoxide and sulfone function is derived from water.
