Check Digit Verification of cas no

The CAS Registry Mumber 21099-60-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,9 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21099-60:
(7*2)+(6*1)+(5*0)+(4*9)+(3*9)+(2*6)+(1*0)=95
95 % 10 = 5
So 21099-60-5 is a valid CAS Registry Number.

Synthesis and nano-Pd catalyzed chemoselective oxidation of symmetrical and unsymmetrical sulfides

Li, Xing,Du, Jia,Zhang, Yongli,Chang, Honghong,Gao, Wenchao,Wei, Wenlong

, p. 3048 - 3055 (2019/03/21)

A highly chemoselective, efficient and nano-Pd catalyzed protocol for the rapid construction of sulfoxides and sulfones via the oxidation of symmetrical and unsymmetrical sulfides using H2O2 as an oxidant has been developed, respectively. The ready availability of starting materials, easy recovery and reutilization of the catalyst, wide substrate scope, and high yields make this protocol an attractive alternative. The process also involves the metal-free and microwave-promoted synthesis of symmetrical diarylsulfides, and FeCl3-mediated preparation of symmetrical diaryldisulfides through the reaction of arenediazonium tetrafluoroborates with Na2S·9H2O as a sulfur source. In addition, unsymmetrical sulfides were generated via the K2CO3-mediated reaction of arenediazonium tetrafluoroborates with symmetrical disulfides.

Palladium-Catalyzed Enantioselective C?H Olefination of Diaryl Sulfoxides through Parallel Kinetic Resolution and Desymmetrization

Zhu, Yu-Chao,Li, Yan,Zhang, Bo-Chao,Zhang, Feng-Xu,Yang, Yi-Nuo,Wang, Xi-Sheng

supporting information, p. 5129 - 5133 (2018/03/27)

The first example of PdII-catalyzed enantioselective C?H olefination with non-chiral or racemic sulfoxides as directing groups was developed. A variety of chiral diaryl sulfoxides were synthesized with high enantioselectivity (up to 99 %) throu

Efficient synthesis of diaryl sulfides by copper-catalysed coupling of aryl halides and thioacetate in water

Zhang, Yimin,Liu, Li,Chen, Junmin

, p. 19 - 21 (2013/04/10)

A simple economical, and highly efficient catalytic system for the synthesis of diaryl sulfides by a copper-catalysed coupling of aryl halides and thioacetate in water has been developed. A variety of aryl halides reacted with thioacetate to give the desired products in high yields up to 95%. The present catalysis protocol tolerated a wide range of functional groups, including amino, fluoro, and carboxyl moieties.

Efficient copper(I)-catalyzed S-arylation of KSCN with aryl halides in PEG-400

Li, Xiaokang,Yuan, Tangjun,Chen, Junmin

experimental part, p. 651 - 655 (2012/05/05)

A simple and efficient protocol for CuI-catalyzed C-S bond formation of aryl halides with KSCN to symmetrical diaryl sulfides was reported in PEG-400 without any other additives. A variety of aryl halides were converted to the corresponding diaryl sulfides in good to excellent yields. The present procedure tolerated a variety of functional groups and the steric hindrance of ortho-substituents on aryl halides did not affect the outcome.

Efficient copper-catalyzed double S-arylation of aryl halides with sodium sulfide in PEG-400

Chen, Junmin,Zhang, Yimin,Liu, Li,Yuan, Tangjun,Yi, Fei

, p. 1284 - 1290 (2012/11/07)

An efficient copper-catalyzed double S-arylation of sodium sulfide with aryl halides in PEG-400 has been developed. With CuI as a catalyst and PEG-400 as a solvent, a range of electron-withdrawing or electron-donating aryl iodides and aryl bromides were found to be applicable to the environmentally benign system. The present procedure is mild and tolerant of a variety of functional groups and the steric hindrance of ortho-substituents on aryl halides did not affect the outcome of good to excellent yields.

A novel and efficient cross-coupling of tris(fluorinated phenyl)boroxins with disulfides catalyzed by CuI/1,10-phenanthroline

Yu, Chuanming,Jin, Beibei,Liu, Zhenyu,Zhong, Weihui

experimental part, p. 485 - 491 (2010/09/17)

Under an oxygen atmosphere, the cross-coupling of tris(fluorinated phenyl)boroxins and disulfides catalyzed by CuI/1,10-phenanthroline were smoothly achieved to produce the corresponding asymmetric fluorinated arylsulfides in good-to-excellent yields.

Preparation process of fluorine substituted aromatic compound

-

, (2008/06/13)

A preparation process of a fluorine substituted aromatic compound comprising reacting an alkali metal or alkali earth metal salt of an aromatic compound having a hydroxy group with an organic fluorinating agent is disclosed. As a representative fluorinating agent, a bis-dialkylamino-difluoromethane compound, for example, 2,2′-difluoro-1,3-dimethylimidazolidine, is exemplified. According to the process, an industrially useful fluorinated aromatic compound, for example, a fluorobenzene, a fluorine substituted benzophenone, a fluorine substituted diarylsulfone can be prepared with ease in economy without specific equipment.
