99071-31-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99071-31-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,7 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99071-31:
(7*9)+(6*9)+(5*0)+(4*7)+(3*1)+(2*3)+(1*1)=155
155 % 10 = 5
So 99071-31-5 is a valid CAS Registry Number.

Bromo Radical-Mediated Photoredox Aldehyde Decarbonylation towards Transition-Metal-Free Hydroalkylation of Acrylamides at Room Temperature

Sun, Zhaozhao,Huang, Huawen,Wang, Qiaolin,Deng, Guo-Jun

supporting information, p. 453 - 458 (2021/12/03)

Herein, we report a visible-light-mediated hydroalkylation reaction of alkenes using easily available aldehydes as alkyl sources via bromo radical-promoted photoredox decarbonylation. This protocol provides an alternative entry to C(sp3)?C(sp3) bond formation and features considerable advantages including mild and clean reaction conditions, obviation for transition-metal catalyst, and good functional group compatibility.

Catalyst-free and selective trifluoromethylative cyclization of acryloanilides using PhICF3Cl

Guo, Jia,Xu, Cong,Wang, Ling,Huang, Wanqiao,Wang, Mang

supporting information, p. 4593 - 4599 (2019/05/17)

Trifluoromethylation-triggered cyclization of alkenes provides a useful route to CF3-containing cyclic compounds. Current approaches to generate CF3-based initiators from a CF3 source require a catalyst or an activator. This work describes a catalyst-free protocol to innately produce electrophilic CF3 species from PhICF3Cl for trifluoromethylative cyclization of acryloanilides. A new domino biscyclization of dienes has been developed leading to trifluoroethylated tetrahydroindenoquinolinones with chemo- and stereo-selectivity.

Synthesis of oxindoles via Cu-mediated reactions between N-phenylacrylamides and ethyl 2-bromo-2-methylpropionate

Liu, Da,Zhuang, Shaobo,Chen, Xiang,Yu, Lin,Yu, Yongqi,Hu, Liang,Tan, Ze

supporting information, p. 612 - 616 (2018/01/18)

A novel way of synthesizing alkylated oxindoles via Cu-mediated atom transfer radical addition reaction between N-phenylacrylamides and ethyl 2-bromo-2-methylpropionate has been described. It was found that the use of N,N,N′,N′-1,1,2,2,-tetramethylethylenediamine as ligand was important for achieving good yields. Additionally, the use of DMSO as solvent and running the reaction at 130 °C were also crucial. In some cases, the product can be further brominated when the reaction temperature was raised to 150 °C.
