177551-63-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 177551-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,5,5 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 177551-63:
(8*1)+(7*7)+(6*7)+(5*5)+(4*5)+(3*1)+(2*6)+(1*3)=162
162 % 10 = 2
So 177551-63-2 is a valid CAS Registry Number.

Oxidative trifluoromethylthiolations of aryl boronic acids using a copper/O2-based protocol

Zhang, Cheng-Pan,Vicic, David A.

, p. 1756 - 1758 (2012)

All you need is air: A new protocol has been developed which can mediate the coupling of aryl and vinyl boronic acids at room temperature in high yields (see scheme, dtbpy=4,4'-di-tert-butyl-2,2'-bipyridine). The reactions take place using simple copper(II) salts under aerobic conditions and do not require the use of expensive silver oxidants.

Gold (I/III)-Catalyzed Trifluoromethylthiolation and Trifluoromethylselenolation of Organohalides

Mudshinge, Sagar R.,Yang, Yuhao,Xu, Bo,Hammond, Gerald B.,Lu, Zhichao

supporting information, (2022/02/10)

The first C?SCF3/SeCF3 cross-coupling reactions using gold redox catalysis [(MeDalphos)AuCl], AgSCF3 or Me4NSeCF3, and organohalides as substrates are reported. The new methodology enables a one-stop shop synthesis of aryl/alkenyl/alkynyl trifluoromethylthio- and selenoethers with a broad substrate scope (>60 examples with up to 97 % isolated yield). The method is scalable, and its robustness is evidenced by the late-stage functionalization of various bioactive molecules, which makes this reaction an attractive alternative in the synthesis of trifluoromethylthio- and selenoethers for pharmaceutical and agrochemical research and development.

Transition-Metal-Free Synthesis of Aryl Trifluoromethyl Thioethers through Indirect Trifluoromethylthiolation of Sodium Arylsulfinate with TMSCF3

Zheng, Changge,Jiang, Chao,Huang, Shuai,Zhao, Kui,Fu, Yingying,Ma, Mingyu,Hong, Jianquan

, p. 6982 - 6986 (2021/09/08)

Herein, we report an indirect trifluoromethylthiolation of sodium arylsulfinates. This transition-metal-free reaction significantly provides an environmentally friendly and practical synthetic method for aryl trifluoromethyl thioethers using commercial Ruppert-Prakash reagent TMSCF3. This approach is also a potential alternative to the current industrial production method owing to facile substrates, excellent functional group compatibility, and operational simplicity.

Preparation method of trifluoromethyl aryl thioether

-

Paragraph 0027; 0036-0038; 0042-0060, (2021/02/20)

The invention discloses a preparation method of trifluoromethyl aryl thioether, and belongs to the field of chemicals for daily use in chemical industry. Aryl sulfinate and trifluoromethyl trimethyl silane are used as substrates, no transition metal catalyst is needed, and trifluoromethyl aryl thioether is obtained through reaction under the action of an additive, an oxidizing agent and alkali. The reaction can be carried out in a room-temperature environment, the reaction is green, simple and convenient, the reaction yield is as high as 55%, and a new approach of a trifluoromethylthiolation indirect method is provided in the field of fluorine chemistry; the obtained product has wide application in the fields of medicines, pesticides and materials.
