2142-64-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2142-64-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,4 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2142-64:
(6*2)+(5*1)+(4*4)+(3*2)+(2*6)+(1*4)=55
55 % 10 = 5
So 2142-64-5 is a valid CAS Registry Number.

Selective Electrochemical Oxygenation of Alkylarenes to Carbonyls

Li, Xue,Bai, Fang,Liu, Chaogan,Ma, Xiaowei,Gu, Chengzhi,Dai, Bin

supporting information, p. 7445 - 7449 (2021/10/02)

An efficient electrochemical method for benzylic C(sp3)-H bond oxidation has been developed. A variety of methylarenes, methylheteroarenes, and benzylic (hetero)methylenes could be converted into the desired aryl aldehydes and aryl ketones in moderate to excellent yields in an undivided cell, using O2 as the oxygen source and lutidinium perchlorate as an electrolyte. On the basis of cyclic voltammetry studies, 18O labeling experiments, and radical trapping experiments, a possible single-electron transfer mechanism has been proposed for the electrooxidation reaction.

Investigations of the generality of quaternary ammonium salts as alkylating agents in direct C-H alkylation reactions: Solid alternatives for gaseous olefins

Sch?nbauer, David,Spettel, Manuel,Pollice, Robert,Pittenauer, Ernst,Schnürch, Michael

supporting information, p. 4024 - 4030 (2019/04/29)

C-H alkylation reactions using short chain olefins as alkylating agents could be operationally simplified on the lab scale by using quaternary ammonium salts as precursors for these gaseous reagents: Hofmann elimination delivers in situ the desired alkenes with the advantage that the alkene concentration in the liquid phase is high. In case a catalytic system did not tolerate the conditions for Hofmann elimination, a very simple spatial separation of both reactions, Hofmann elimination and direct alkylation, was achieved to circumvent possible side reactions or catalyst deactivation. Additionally, the truly catalytically active species of a rhodium(i) mediated alkylation reaction could be identified by using this approach.

Quaternary Ammonium Salts as Alkylating Reagents in C-H Activation Chemistry

Spettel, Manuel,Pollice, Robert,Schnürch, Michael

, p. 4287 - 4290 (2017/08/23)

A rhodium(I)-catalyzed alkylation reaction of benzylic amines via C(sp3)-H activation using quaternary ammonium salts as alkyl source is described. The reaction proceeds via in situ formation of an olefin via Hofmann elimination, which is the actual alkylating reagent. This represents an operationally simple method for substituting gaseous and liquid olefins with solid quaternary ammonium salts as alkylating reagents, which is transferable to other C-H activation protocols as well.
