842120-98-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 842120-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,2,1,2 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 842120-98:
(8*8)+(7*4)+(6*2)+(5*1)+(4*2)+(3*0)+(2*9)+(1*8)=143
143 % 10 = 3
So 842120-98-3 is a valid CAS Registry Number.

Asymmetric Stepwise Reductive Amination of Sulfonamides, Sulfamates, and a Phosphinamide by Nickel Catalysis

Zhao, Xiaohu,Xu, Haiyan,Huang, Xiaolei,Zhou, Jianrong Steve

supporting information, p. 292 - 296 (2018/12/13)

Asymmetric reductive amination of poorly nucleophilic sulfonamides was realized in the presence of nickel catalysts and titanium alkoxide. A wide range of ketones, including enolizable ketones and some biaryl ones, were converted into sulfonamides in excellent enantiomeric excess. The cyclization of sulfamates and intermolecular reductive amination of a diarylphosphinamide were also successful. Formic acid was used as a safe and economic surrogate of high-pressure hydrogen gas.

Direct Synthesis of Enolizable N-Sulfonyl Ketimines under Microwave Irradiation

Ortiz, Pablo,Collados, Juan F.,Harutyunyan, Syuzanna R.

supporting information, p. 1247 - 1250 (2016/03/19)

N-sulfonyl imines are widely used as substrates for a range of transformations. Access to N-sulfonyl aldimines is straightforward through direct condensation between the parent aldehyde and the sulfonamide. However, this approach is not efficient for the

Reduction of sulfonylimines with raney nickel

Ruano, Jose Luis Garca,Fernandez-Salas, Jose A.,Maestro, M. Carmen,Parra, Alejandro

, p. 198 - 207,10 (2020/09/02)

Raney-Ni/EtOH reduction of different N-sulfonylimines provides a new entry for synthesizing sulfonamides in good yields under mild conditions. This protocol, which does not require additional hydrogen, constitutes a cheap, safe, and easy-to-handle alterna
