857839-66-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 857839-66-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,8,3 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 857839-66:
(8*8)+(7*5)+(6*7)+(5*8)+(4*3)+(3*9)+(2*6)+(1*6)=238
238 % 10 = 8
So 857839-66-8 is a valid CAS Registry Number.

A facile and versatile electro-reductive system for hydrodefunctionalization under ambient conditions

Huang, Binbin,Guo, Lin,Xia, Wujiong

supporting information, p. 2095 - 2103 (2021/03/26)

A general electrochemical system for reductive hydrodefunctionalization is described, employing the inexpensive and easily available triethylamine (Et3N) as a sacrificial reductant. This protocol is characterized by facile operation, sustainable conditions, and exceptionally wide substrate scope covering the cleavage of C-halogen, N-S, N-C, O-S, O-C, C-C and C-N bonds. Notably, the selectivity and capability of reduction can be conveniently switched by simple incorporation or removal of an alcohol as a co-solvent.

Palladium-Catalyzed Carbonylative Esterification of Primary Alcohols with Aryl Chlorides through Dehydroxymethylative C-C Bond Cleavage

Park, Hyo-Soon,Kim, Dong-Su,Jun, Chul-Ho

, p. 397 - 401 (2015/04/27)

Aryl chlorides in the presence of Pd/C catalyst and NaF react with primary alcohols to form esters, arenes, and alkanes. In this reaction, aryl chlorides act as both oxidants and coupling partners, whereas alcohols serve as both carbonyl sources and alkoxy components of the ester products. (Formula Presented).

Suzuki-miyaura cross-coupling reactions of primary alkyltrifluoroborates with aryl chlorides

Dreher, Spencer D.,Lim, Siang-Ee,Sandrock, Deidre L.,Molander, Gary A.

supporting information; experimental part, p. 3626 - 3631 (2009/09/29)

(Chemical Equation Presented) Parallel microscale experimentation was used to develop general conditions for the Suzuki-Miyaura cross-coupling of diversely functionalized primary alkyltrifluoroborates with a variety of aryl chlorides. These conditions wer
