42057-02-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42057-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,5 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 42057-02:
(7*4)+(6*2)+(5*0)+(4*5)+(3*7)+(2*0)+(1*2)=83
83 % 10 = 3
So 42057-02-3 is a valid CAS Registry Number.

Coupling of thiols and aromatic halides promoted by diboron derived super electron donors

Franco, Mario,Vargas, Emily L.,Tortosa, Mariola,Cid

supporting information, p. 11653 - 11656 (2021/11/12)

We have proven that pyridine-boryl complexes can be used as superelectron donors to promote the coupling of thiols and aromatic halides through a SRN1 mechanism. The reaction is efficient for a broad substrate scope, tolerating heterocycles including pyridines, enolizable or reducible functional groups. The method has been applied to intermediates in drug synthesis as well as interesting functionalized polythioethers through a controlled and consecutive intramolecular electron transfer process.

Redox-active benzimidazolium sulfonamides as cationic thiolating reagents for reductive cross-coupling of organic halides

Zhang, Weigang,Huang, Mengjun,Zou, Zhenlei,Wu, Zhengguang,Ni, Shengyang,Kong, Lingyu,Zheng, Youxuan,Wang, Yi,Pan, Yi

, p. 2509 - 2514 (2021/03/01)

Redox-active benzimidazolium sulfonamides as thiolating reagents have been developed for reductive C-S bond coupling. The IMDN-SO2R reagent provides a bench-stable cationic precursor to generate a portfolio of highly active N-S intermediates, which can be successfully applied in cross-electrophilic coupling with various organic halides. The employment of an electrophilic sulfur source solved the problem of catalyst deactivation and avoided odorous thiols, featuring practical conditions, broad substrate scope, and excellent tolerance.

Rhodium-catalyzed odorless synthesis of diaryl sulfides from borylarenes and: S -aryl thiosulfonates

Kanemoto, Kazuya,Sugimura, Yasuyuki,Shimizu, Shigeomi,Yoshida, Suguru,Hosoya, Takamitsu

supporting information, p. 10640 - 10643 (2017/10/06)

Various diaryl sulfides, including heteroaryl- and nitrogen-containing sulfides, have been efficiently prepared by rhodium-catalyzed odorless deborylative arylthiolation of organoborons with S-aryl thiosulfonates. The ready availability of starting materials and further transformation of sulfides have rendered a diverse range of organosulfur compounds easily accessible.
