50609-23-9 Usage

General Description

2,6-Dichlorobenzophenone is a chemical compound with the molecular formula C13H8Cl2O. It is a white crystalline solid that is insoluble in water and commonly used as an intermediate in the production of pharmaceuticals and agrochemicals. It is also used as a photoinitiator in the production of inks, adhesives, and coatings. 2,6-Dichlorobenzophenone is classified as a hazardous substance and should be handled with care due to its potential health and environmental risks. It can cause skin and eye irritation, and long-term exposure may have adverse effects on human health. Additionally, it is harmful to aquatic organisms and can cause long-term damage to the aquatic environment.

Check Digit Verification of cas no

The CAS Registry Mumber 50609-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,0 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 50609-23:
(7*5)+(6*0)+(5*6)+(4*0)+(3*9)+(2*2)+(1*3)=99
99 % 10 = 9
So 50609-23-9 is a valid CAS Registry Number.

Kinetically Controlled, Highly Chemoselective Acylation of Functionalized Grignard Reagents with Amides by N?C Cleavage

Li, Guangchen,Szostak, Michal

supporting information, p. 611 - 615 (2020/01/02)

The direct transition-metal-free acylation of amides with functionalized Grignard reagents by highly chemoselective N?C cleavage under kinetic control has been accomplished. The method offers rapid and convergent access to functionalized biaryl ketones through transient tetrahedral intermediates. The direct access to functionalized Grignard reagents by in situ halogen–magnesium exchange promoted by the versatile turbo-Grignard reagent (iPrMgCl?LiCl) permits excellent substrate scope with respect to both the amide and Grignard coupling partners. These reactions enable facile, operationally simple and chemoselective access to tetrahedral intermediates from amides under significantly milder conditions than chelation-controlled intermediates. This novel direct two-component coupling sets the stage for using amides as acylating reagents in an alternative paradigm to the metal-chelated approach, acyl metals and Weinreb amides.

Synthesis of (2-chlorophenyl)(phenyl)methanones and 2-(2-chlorophenyl)-1- phenylethanones by Friedel-Crafts acylation of 2-chlorobenzoic acids and 2-(2-chlorophenyl)acetic acids using microwave heating

Mahdi, Jasia,Ankati, Haribabu,Gregory, Jill,Tenner, Brian,Biehl, Edward R.

experimental part, p. 2594 - 2596 (2011/06/21)

Several 2-(2-chlorophenyl)-1-phenylethanones and (2-chlorophenyl)(phenyl) methanones were prepared by the Friedel-Crafts acylation reaction of 2-(2-chlorophenyl) acetic acids and 2-chlorocarboxylic acids, respectively, in the presence of cyanuric chloride, pyridine, and AlCl3 or FeCl 3 using microwave heating. The yields of the ketones were significantly higher than those obtained using conventional heating. In addition, similar reactions carried out with the less inexpensive and less toxic FeCl3 gave titled ketones in comparable yields. Interestingly, the FeCl3 catalyzed reactions gave pure ketones (no chromatographic purification required), whereas the AlCl3 catalyzed reaction gave impure product that required chromatographic purification.

Triflic acid catalyzed aroylation of arenes with aromatic nitriles

El-Khagawa, Ahmed M.

, p. 372 - 374 (2007/10/02)

In the presence of triflic acid, the reaction of different aromatic nitriles with arenes under a variety of conditions was examined.In addition to the normal reaction products (the s-triazines), aroylation of the arene to produce diaryl ketones in 20 to 50 percent yield was observed.Possible mechanism for the reaction was proposed.
