120977-75-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 120977-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,7 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120977-75:
(8*1)+(7*2)+(6*0)+(5*9)+(4*7)+(3*7)+(2*7)+(1*5)=135
135 % 10 = 5
So 120977-75-5 is a valid CAS Registry Number.

Unbalanced-Ion-Pair-Catalyzed Nucleophilic Fluorination Using Potassium Fluoride

Hammond, Gerald B.,Li, Wangbing,Lu, Zhichao,Xu, Bo

, p. 9640 - 9644 (2021/12/14)

An unbalanced ion pair promoter (e.g., tetrabutylammonium sulfate), consisting of a bulky and charge-delocalized cation and a small and charge-localized anion, greatly accelerates nucleophilic fluorinations using easy handling KF. We also successfully converted an inexpensive and commercially available ion-exchange resin to the polymer-supported ion pair promoter (A26–SO42–), which could be reused after filtration. Moreover, A26–SO42– can be used in continuous flow conditions. In our conditions, water is well-tolerated.

Electrolytic Reactions of Fluoroorganic Compounds. 14. Regioselective Anodic Methoxylation of N-(Fluoroethyl)amines. Preparation of Highly Useful Fluoroalkylated Building Blocks

Fuchigami, Toshio,Ichikawa,, Shinji

, p. 607 - 615 (2007/10/02)

Anodic methoxylation of various types of N-(fluoroethyl)amines, ArRNCH2Rf (Rf = CF3, CHF2, CH2F, etc.) has been systematically studied and it was found that a methoxy group was exclusively or preferentially introduced into the position α to the fluoromethyl (Rf) group, depending on the Rf and R groups.The effect of the Rf group on the promotion of the anodic α-methoxylation decreased in the order CF3, CHF2, and CH2F.This remarkable promotion effect and unique regioselectivity can be explained mainly in terms of the α-CH kinetic acidities of the cation radicals formed by one-electron oxidation of the amines.The α-methoxylated products are highly useful precursors for the construction of carbon-carbon bonds α to the trifluoromethyl and difluoromethyl groups, which is difficult by other methods.
