31401-23-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31401-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,0 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31401-23:
(7*3)+(6*1)+(5*4)+(4*0)+(3*1)+(2*2)+(1*3)=57
57 % 10 = 7
So 31401-23-7 is a valid CAS Registry Number.

Regio- and Stereoselective Chloro Sulfoximidations of Terminal Aryl Alkynes Enabled by Copper Catalysis and Visible Light

Shi, Peng,Tu, Yongliang,Zhang, Duo,Wang, Chenyang,Truong, Khai-Nghi,Rissanen, Kari,Bolm, Carsten

supporting information, p. 2552 - 2556 (2021/03/19)

By visible-light photoredox catalysis with copper complexes, sulfoximidoyl chlorides add to terminal aryl alkynes to give the corresponding (E)-β-chlorovinyl sulfoximines with exclusive regio- and stereoselectivities in high yields. Two representative pro

A New, Practical One-Pot Synthesis of Unprotected Sulfonimidamides by Transfer of Electrophilic NH to Sulfinamides

Izzo, Flavia,Sch?fer, Martina,Stockman, Robert,Lücking, Ulrich

supporting information, p. 15189 - 15193 (2017/10/12)

Unprotected tertiary sulfonimidamides have been prepared in good to excellent yields in a one-pot transformation from tertiary sulfinamides through NH transfer. The reaction is mediated by commercially available (diacetoxyiodo)benzene and ammonium carbamate in methanol under convenient conditions. A wide range of functional groups are tolerated and initial results indicate that the NH transfer is stereospecific. A small molecule X-ray analysis of NH sulfonimidamide 2 a and its behavior in selected in vitro assays in comparison to the matched sulfonamide are also reported. This new reaction provides a safe, short and efficient approach to sulfonimidamides, which have been the subject of recent, growing interest in the life sciences.

Serial ligand catalysis: A highly selective allylic C-H oxidation

Chen, Mark S.,Prabagaran, Narayanasamy,Labenz, Nathan A.,White, M. Christina

, p. 6970 - 6971 (2007/10/03)

We are reporting a mild, chemo-, and highly regioselective Pd(II)-catalyzed allylic oxidation of α-olefins to furnish branched allylic esters that proceeds via a novel serial ligand catalysis mechanism in which two different ligands (i.e., vinyl sulfoxide 2 and BQ) interact sequentially with the metal to promote distinct steps of the catalytic cycle (i.e., C-H cleavage and π-allyl functionalization, respectively).
