61820-94-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 61820-94-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,8,2 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 61820-94:
(7*6)+(6*1)+(5*8)+(4*2)+(3*0)+(2*9)+(1*4)=118
118 % 10 = 8
So 61820-94-8 is a valid CAS Registry Number.

Copper-catalyzed aerobic oxidative cross-coupling reactions of vinylarenes with sulfinate salts: A direct approach to β-ketosulfones

Chen, Yu,Xu, Lei,Wang, Biyu,Jiang, Jingjing,Sun, Yixiang,Li, Longchun

, (2021/01/25)

A copper-catalyzed aerobic oxidative cross-coupling reactions for the synthesis of β-ketosulfones via formation of a C[sbnd]S bond has been demonstrated. Promoted by the crucial copper catalyst, perfect selectivity and good to excellent yields could be achieved. This method, including inexpensive copper catalyst, wide functional group tolerance, and open air conditions, make it very attractive and practical. More importantly, it also provides a versatile tool for the construction of β-ketosulfones from basic starting materials under mild conditions.

Dioxygen-Triggered Oxosulfonylation/Sulfonylation of Terminal Olefins toward β-Keto Sulfones/Sulfones

supporting information, p. 8296 - 8301 (2021/11/13)

A dioxygen-triggered oxosulfonylation/sulfonylation of unactivated olefins to achieve β-keto sulfones/sulfones has been developed. Interestingly, pluralistic mechanisms were found when different types of compounds were applied as substrates, and different products were achieved. The reaction is carried out with a high atomic efficiency in the absence of a metal and a catalyst at room temperature under an air atmosphere. Importantly, as a proof-of-concept, a bioactive molecule was synthesized on a gram-scale level using this method.

Cu(OTf)2-Catalyzed efficient sulfonylation of vinyl azides with sodium sulfinates

Ning, Zhitao,Xu, Zheng,Liu, Ruikai,Du, Zhengyin

supporting information, p. 3492 - 3500 (2021/10/14)

A simple oxidative cross-coupling reaction between vinyl azides and sodium sulfinates was developed. This reaction uses commercial arylsulfinates that are more efficient, cheaper, and more stable as sulfonylation reagents, for efficiently, cheaply, and environmentally friendly synthesis of β-keto sulfones. And the reaction has the advantages of simple operation, high efficiency, good yield, and also has a wide range of functional group tolerance.
