73471-97-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73471-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,7 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73471-97:
143 % 10 = 3
So 73471-97-3 is a valid CAS Registry Number.

Trifluoromethylation of Benzoic Acids: An Access to Aryl Trifluoromethyl Ketones

Liu, Xue,Liu, Long,Huang, Tianzeng,Zhang, Jingjing,Tang, Zhi,Li, Chunya,Chen, Tieqiao

supporting information, p. 4930 - 4934 (2021/06/30)

The trifluoromethylation of benzoic acids with TMSCF3 was achieved through nucleophilic substitution with the use of anhydrides as an in situ activating reagent. Under the reaction conditions, a wide range of carboxylic acids including the bioactive ones worked well, thus providing a facile and efficient method for preparing aryl trifluoromethyl ketones from the readily available starting materials.

Decarboxylative and Deaminative Alkylation of Difluoroenoxysilanes via Photoredox Catalysis: A General Method for Site-Selective Synthesis of Difluoroalkylated Alkanes

Song, Heng,Cheng, Ran,Min, Qiao-Qiao,Zhang, Xingang

supporting information, p. 7747 - 7751 (2020/10/09)

A general method for site-selective difluoroalkylation of alkyl carboxylic redox esters with difluoroenoxysilanes through photoredox-catalyzed decarboxylative reaction has been developed. The reaction can also be extended to aliphatic amine derived pyridinium salts. This method has the advantages of high efficiency, mild reaction conditions, and broad substrate scope, including primary, secondary, and sterically hindered tertiaryl alkyl substrates, providing a general and practical route for applications in organic synthesis and pharmaceutical studies.

N-phenyl-N-p-toluenesulfonyl trifluoroacetamide (NTFTS) and application


Paragraph 0048-0051, (2019/08/02)

The invention belongs to the technical field of medical chemical engineering intermediates and related chemistry, and relates to N-phenyl-N-p-toluenesulfonyl trifluoroacetamide (NTFTS) and application. The N-phenyl-N-p-toluenesulfonyl trifluoroacetamide is taken as a trifluoroacetylation reagent, reacts with an arylboronic acid derivative in an anhydrous organic solvent under the action of a metalcatalyst, a ligand and an alkali, and is efficiently and highly selectively converted into a trifluoroacetophenone compound. According to a synthesis method of the trifluoroacetophenone compound, involved in the invention, reaction steps are few; the NTFTS which is stable in use, easy to store, cheap and easy to get is taken as a trifluoroacetyl source; environmental friendliness is realized; reaction conditions are mild; operation is easy; a high-yield and high-selectivity target product is obtained and has relatively good industrial production value and practical application value. The trifluoroacetophenone compound synthesized by utilizing the method can be further subjected to a functionalization reaction, and can be widely applied to the synthetic fields of medicine, pesticide, bioactive molecules, functional material molecules and the like.
