28321-12-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28321-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,3,2 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 28321-12:
(7*2)+(6*8)+(5*3)+(4*2)+(3*1)+(2*1)+(1*2)=92
92 % 10 = 2
So 28321-12-2 is a valid CAS Registry Number.

Stereoselective formation of Z-monofluoroalkenes by nickel-catalyzed defluorinative coupling of gem?difluoroalkenes with lithium organoborates

Huang, Weichen,Shen, Qilong,Xiao, Yisa

supporting information, (2022/02/02)

A method for stereoselective construction of Z-monofluoroalkenes by nickel-catalyzed defluorinative coupling of gem?difluoroalkenes in mild conditions was described. The combination of lithium organoborate and ZnBr2 generated in situ lithium ar

Ni-Catalyzed Defluorination for the Synthesis of gem-Difluoro-1,3-dienes and Their [4 + 2] Cycloaddition Reaction

Zhou, Minqi,Zhang, Jian,Zhang, Xing-Guo,Zhang, Xingang

, p. 671 - 674 (2019/01/21)

A nickel-catalyzed defluorination of α-trifluoromethylated allyl/propargyl carbonates using bis(pinacolato)diboron (B2pin2) as a reactant is described. The reaction proceeds under relatively mild reaction conditions, providing conjug

Copper-Catalyzed Regioselective Monodefluoroborylation of Polyfluoroalkenes en Route to Diverse Fluoroalkenes

Sakaguchi, Hironobu,Uetake, Yuta,Ohashi, Masato,Niwa, Takashi,Ogoshi, Sensuke,Hosoya, Takamitsu

supporting information, p. 12855 - 12862 (2017/09/25)

Monodefluoroborylation of polyfluoroalkenes has been achieved in a regioselective manner under mild conditions via copper catalysis. The method has shown an extremely broad scope of substrates, including (difluorovinyl)arenes, tetrafluoroethylene (TFE), (
