885-89-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 885-89-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,8 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 885-89:
(5*8)+(4*8)+(3*5)+(2*8)+(1*9)=112
112 % 10 = 2
So 885-89-2 is a valid CAS Registry Number.

Oxidation Potential-Guided Electrochemical Radical-Radical Cross-Coupling Approaches to 3-Sulfonylated Imidazopyridines and Indolizines

Kim, Wansoo,Kim, Hun Young,Oh, Kyungsoo

, p. 15973 - 15991 (2021/07/26)

Oxidation potential-guided electrochemical radical-radical cross-coupling reactions between N-heteroarenes and sodium sulfinates have been established. Thus, simple cyclic voltammetry measurement of substrates predicts the likelihood of successful radical-radical coupling reactions, allowing the simple and direct synthetic access to 3-sulfonylated imidazopyridines and indolizines. The developed electrochemical radical-radical cross-coupling reactions to sulfonylated N-heteroarenes boast the green synthetic nature of the reactions that are oxidant- and metal-free.

Micellar Catalysis: Visible-Light Mediated Imidazo[1,2-a]pyridine C—H Amination with N-Aminopyridinium Salt Accelerated by Surfactant in Water

Yang, Zhonglie,Cao, Kun,Peng, Xiaoyan,Lin, Li,Fan, Danchen,Li, Jun-Long,Wang, Jingxia,Zhang, Xiaobin,Jiang, Hezhong,Li, Jiahong

supporting information, p. 3347 - 3352 (2021/10/20)

A light-promoted metal-free protocol for the amination of imidazo[1,2-a]pyridines with N-aminopyridinium salt by the assistance of surfactants in water was reported, charactering mild and environmentally benign conditions, as well as great functional grou

Multicomponent Synthesis of Imidazo[1,2- a]pyridines: Aerobic Oxidative Formation of C-N and C-S Bonds by Flavin-Iodine-Coupled Organocatalysis

Okai, Hayaki,Tanimoto, Kazumasa,Ohkado, Ryoma,Iida, Hiroki

supporting information, p. 8002 - 8006 (2020/11/02)

Herein, we report an aerobic oxidative C-N bond-forming process that enables the facile synthesis of imidazo[1,2-a]pyridines and takes advantage of a coupled organocatalytic system that uses flavin and iodine. Furthermore, the dual catalytic system can be applied to the one-pot, three-step synthesis of 3-thioimidazo[1,2-a]pyridines from aminopyridines, ketones, and thiols.
