Check Digit Verification of cas no

The CAS Registry Mumber 4953-10-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,5 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4953-10:
(6*4)+(5*9)+(4*5)+(3*3)+(2*1)+(1*0)=100
100 % 10 = 0
So 4953-10-0 is a valid CAS Registry Number.

Mechanistic investigations on C-H activated dealkylating cyclo-amination reactions of substituted triazenes, formamidines and amidines

Preusser, Silvio,Kalden, Diana,Wendler, Felix,Sch?nherr, Paul R. W.,G?rls, Helmar,Westerhausen, Matthias,Imhof, Wolfgang

, p. 651 - 664 (2020/07/27)

Catalytic dealkylating cycloamination reactions of N 1-methylated-N 1,N 3-diarylated triazenes proceed via two subsequent oxidative addition reactions, regioselectivity producing benzotriazoles by C-H and C-Br activation steps. Whereas palladium-based catalysis in the presence of dealkylating reagents and directing phosphane ligands leads to high yields, the homologous metals nickel and platinum as well as other 3d transition metals show only poor catalytic activity in similar procedures. Starting compounds have been widely varied to introduce potentially competing reaction sites and to investigate the reaction mechanism of the catalytic cyclization reactions. Yields of the benzotriazole synthesis strongly depend on the electronic and steric properties of the directing phosphane ligands, the nature of the dealkylating bases and the substitution pattern in 2- A nd 4-position of the aryl groups of the starting triazenes. In order to clarify the role of the catalyst, palladium-based intermediates were identified. Finally, formamidines and bulky amidines were tested in related C-H activated dealkylating cycloamination reactions.

Cu-catalyzed arylation of 1-acyl-1H-1,2,3-Benzotriazoles via C–N activation

Zhang, Wenying,Wang, Yangyang,Jia, Xiangru,Du, Zhengyin,Fu, Ying

, p. 64 - 67 (2019/06/10)

An efficient copper-catalyzed arylation reaction of 1-acyl-1H-1,2,3-benzotriazoles with diaryliodonium salts via C–N activation is explored. The reaction is conducted regioselectively to form 1-aryl-1H-1,2,3-benzotriazoles in MeCN at 80 °C in the presence of cesium carbonate. 29 examples are given with the product yield of up to 84%. The probable reaction mechanism is proposed.

The Disappearing Director: The Case of Directed N-Arylation via a Removable Hydroxyl Group

Andrzejewska, Magdalena R.,Vuram, Prasanna K.,Pottabathini, Narender,Gurram, Venkateshwarlu,Relangi, Siva Subrahmanyam,Korvinson, Kirill A.,Doddipalla, Raju,Stahl, Lothar,Neary, Michelle C.,Pradhan, Padmanava,Sharma, Somesh,Lakshman, Mahesh K.

, p. 2503 - 2510 (2018/05/08)

A facile and broadly applicable method for the regiospecific N-arylation of benzotriazoles is reported. Copper-mediated reactions of diverse 1-hydroxy-1H-benzotriazoles with aryl boronic acids lead to 1-aryl-1H-benzotriazole 3-oxides. A N1-OH→N3 prototropy in the 1-hydroxy-1H-benzotriazoles is plausibly the underlying basis, where the tautomer is captured by the boronic acid, leading to C?N (not C?O) bond formation. Because the N?O bond in amine N-oxides and 1-hydroxy-1H-benzotriazoles can be easily reduced by diboron reagents such as (pinB)2 and B2(OH)4, exposure of the 1-aryl-1H-benzotriazole 3-oxides to B2(OH)4 then leads to facile reduction of the N?O bond resulting in diverse, regiospecifically-arylated benzotriazoles. Thus, the N-hydroxyl group in 1-hydroxy-1H-benzotriazoles acts as a disposable arylation director. (Figure presented.).

Photochemical C–H Activation: Generation of Indole and Carbazole Libraries, and First Total Synthesis of Clausenawalline D

Alimi, Isak,Remy, Richard,Bochet, Christian G.

, p. 3197 - 3210 (2017/06/21)

The photolysis of N-aryltriazoles and N-arylbenzotriazoles leads to indoles and carbazoles, respectively. Because libraries of triazoles can be accessed rapidly, for example by the copper-catalyzed [3+2] cycloaddition reaction between alkynes and azides, this reaction allows the preparation of indoles in a single operation, by the simultaneous photolysis of the precursor library. As an example of such a synthesis of carbazoles, we prepared for the first time clausenawalline D, an antimalarial alkaloid that was recently isolated.

Oxidation-induced C-H amination leads to a new avenue to build C-N bonds

Yi, Hong,Tang, Zilu,Bian, Changliang,Chen, Hong,Qi, Xiaotian,Yue, Xiaoyu,Lan, Yu,Lee, Jyh-Fu,Lei, Aiwen

supporting information, p. 8984 - 8987 (2017/08/15)

In this work, we develop an oxidation-induced C-H functionalization strategy, which not only leads to a new avenue to build C-N bonds, but also leads to different site-selectivity compared with "classic directing-groups". The high selectivity of our new catalytic system originates from the heterogeneous electron-density distribution of the radical cation species which are induced by single electron transfer between the aromatics and oxidant-Cu(ii) species.

Teaching Old Compounds New Tricks: DDQ-Photocatalyzed C?H Amination of Arenes with Carbamates, Urea, and N-Heterocycles

Das, Somnath,Natarajan, Palani,K?nig, Burkhard

supporting information, p. 18161 - 18165 (2017/12/28)

The C?H amination of benzene derivatives was achieved using DDQ as photocatalyst and BocNH2 as the amine source under aerobic conditions and visible light irradiation. Electron-deficient and electron-rich benzenes react as substrates with moderate to good product yields. The amine scope of the reaction comprises Boc-amine, carbamates, pyrazoles, sulfonimides and urea. Preliminary mechanistic investigations indicate arene oxidation by the triplet of DDQ to radical cations with different electrophilicity and a charge transfer complex between the amine and DDQ as intermediate of the reaction.
