1835-61-6 Usage

General Description

1-Chloro-2,3,5,6-tetrafluorobenzene is a chemical compound with the molecular formula C6H2ClF4. It is a colorless liquid with a strong odor, and it is primarily used as an intermediate in the production of pharmaceuticals, agrochemicals, and other industrial chemicals. 1-Chloro-2,3,5,6-tetrafluorobenzene also has potential applications as a solvent and as a reagent in organic synthesis. It is important to handle this compound with care, as it is considered to be hazardous to human health and the environment. Exposure should be minimized, and proper protective measures should be taken when working with 1-chloro-2,3,5,6-tetrafluorobenzene.

Check Digit Verification of cas no

The CAS Registry Mumber 1835-61-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1835-61:
(6*1)+(5*8)+(4*3)+(3*5)+(2*6)+(1*1)=86
86 % 10 = 6
So 1835-61-6 is a valid CAS Registry Number.

Diazaphospholene-Catalyzed Hydrodefluorination of Polyfluoroarenes with Phenylsilane via Concerted Nucleophilic Aromatic Substitution

Zhang, Jingjing,Zhao, Xiao,Yang, Jin-Dong,Cheng, Jin-Pei

supporting information, p. 294 - 300 (2022/01/03)

The metal-free catalytic C-F bond activation of polyfluoroarenes was achieved with diazaphospholene as the catalyst and phenylsilane as the terminal reductant. Density functional theory calculations suggested a concerted nucleophilic aromatic substitution mechanism.

Synthesis of chloropolyfluoroarenes from polyfluoroarenethiols and PCl5

Nikul'shin,Maksimov,Platonov

, p. 200 - 205 (2016/04/19)

Replacement of the thiol group in polyfluoroarenethiols with chlorine was performed by treating with PCl5 as chlorinating agent. By heating in ampules at 200-220°C polyfluoro- and polyfluorochloroarenethiols with PCl5 mono- and dichloropolyfluoroarenes and also 1,2,4-trifluorotrichlorobenzene were synthesized. Dichloropolyfluoroarenes contain chlorine atoms in ortho- and para-positions.

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 ?).
