1,2,5-trifluoro-3-nitrobenzene is a chemical compound with the molecular formula C6H3F3NO2. It is a colorless liquid with a strong, pungent odor. This chemical is primarily used as an intermediate in the production of pharmaceuticals, agrochemicals, and dyes. It is also used as a solvent in various industrial processes. 1,2,5-trifluoro-3-nitrobenzene is classified as a hazardous substance and should be handled with caution due to its potential health and environmental risks. It is important to follow proper safety protocols when working with this chemical to minimize the risk of exposure.

Check Digit Verification of cas no

The CAS Registry Mumber 66684-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,8 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66684-57:
(7*6)+(6*6)+(5*6)+(4*8)+(3*4)+(2*5)+(1*7)=169
169 % 10 = 9
So 66684-57-9 is a valid CAS Registry Number.

Copper-catalyzed hydrodefluorination of fluoroarenes by copper hydride intermediates

Lv, Hongbin,Cai, Yuan-Bo,Zhang, Jun-Long

supporting information, p. 3203 - 3207 (2013/04/23)

Breaking bad: Efficient copper-catalyzed C-F bond activation has been achieved by replacing fluorine with hydrogen. A copper hydride is proposed as the active intermediate, which proceeds through a nucleophilic attack on the fluorocarbon, as determined by experimental and theoretical results (see structure; C gray, H white, Cu light red, F light blue; distances in ?).

Catalytic C-F bond activation of perfluoroarenes by tricoordinated gold(I) complexes

Zhan, Jin-Hui,Lv, Hongbin,Yu, Yi,Zhang, Jun-Long

experimental part, p. 1529 - 1541 (2012/07/14)

We report the first example of gold catalyzing C-F bond activation for perfluoroarenes in the presence of silanes. Tricoordinated gold(I) complexes supported by Xantphos-type ligands, such as Xantphos and tBuXantphos ligands, exhibit efficacy in the hydrodefluorination (HDF) of various types of perfluoroarenes. For [tBuXantphosAu(AuCl2)], the highest turnover number is up to 1000 in the HDF of pentafluoronitrobenzene with diphenylsilane. An examination of functional group tolerance shows the orthogonality of this gold(I) catalytic protocol to ketone, ester, carboxylate, alkynyl, alkenyl and amide groups, suggesting its potential application in chemoselective C-F activations. Mechanistic studies show that the equilibrium between tetracoordinated [L2Au]+ and [LAu]+ is important for the reactivity of gold catalysts, which is dependent on the sterically bulky group of Xantphos-type ligands. Furthermore, computational studies for the possible reaction pathways suggest that direct oxidative addition of C-F bonds by gold(I) cation might be the key step during these catalytic reactions.
