20386-33-8 Usage

General Description

2,3,4,5,6-Pentamethylbenzophenone is a chemical compound used primarily as a UV absorber in various industrial and consumer products. It is a highly effective photoinitiator, meaning it can initiate or catalyze a chemical reaction under the influence of light, making it useful in the production of plastics, adhesives, and coatings. It is also used as a fragrance ingredient in perfumes and personal care products. However, there are concerns about its potential environmental and health effects, as it has been found to persist in the environment and bioaccumulate in organisms. Therefore, regulatory agencies have placed restrictions on its use in some applications, and further research is ongoing to better understand its potential risks.

Check Digit Verification of cas no

The CAS Registry Mumber 20386-33-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,8 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20386-33:
(7*2)+(6*0)+(5*3)+(4*8)+(3*6)+(2*3)+(1*3)=88
88 % 10 = 8
So 20386-33-8 is a valid CAS Registry Number.

Pd(II)-Catalyzed Denitrogenative and Desulfinative Addition of Arylsulfonyl Hydrazides with Nitriles

Meng, Mengting,Yang, Liangfeng,Cheng, Kai,Qi, Chenze

, p. 3275 - 3284 (2018/03/25)

A Pd(II)-catalyzed denitrogenative and desulfinative addition of arylsulfonyl hydrazides with nitriles has been successfully achieved under mild conditions. This transformation is a new method for the addition reaction to nitriles with arylsulfonyl hydrazides as arylating agent, thus providing an alternative synthesis of aryl ketones. The reported addition reaction is tolerant to many common functional groups, and works well in the presence of electron-donating and electron-withdrawing substituents. Notably, the reported denitrogenative and desulfinative addition was also appropriate for alkyl nitriles, making this newly developed transformation attractive.

Method for preparing aromatic ketone in aqueous phase

-

Paragraph 0046-0049, (2018/04/26)

The invention discloses a method for preparing aromatic ketone in an aqueous phase, comprising the following steps: enabling aryl formyl potassium formate and aryl potassium fluoborate to generate decarboxylation acylation reaction in water under the actions of a silver catalyst and an oxidizing agent, and performing treatment after reaction is ended to obtain the disclosed aromatic ketone. According to the preparation method, the silver catalyst replaces a noble metal catalyst, water is taken as a solvent, an aromatic ketone product is obtained with relatively high yield, the adopted catalystis low in cost and easy to obtain, reaction conditions are mild, and meanwhile, the product is good in university, and therefore, the method has good application potential.

Carbonylative coupling of aryl tosylates/triflates with arylboronic acids under CO atmosphere

Hao, Cheng Yi,Wang, Dan,Li, Ya Wei,Dong, Lin Lin,Jin, Ying,Zhang, Xiu Rong,Zhu, He Yun,Chang, Sheng

, p. 86502 - 86509 (2016/09/23)

The carbonylative Suzuki-Miyaura reaction between aryl tosylates/triflates with arylboronic acid is herein reported, using base-free conditions and a balloon pressure of carbon monoxide. Under these conditions, unsymmetrical biaryl ketones were obtained in modest to excellent yields. This method was adapted to the synthesis of oxybenzone and ketoprofen in good yields under mild conditions.
