68253-26-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68253-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,5 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 68253-26:
(7*6)+(6*8)+(5*2)+(4*5)+(3*3)+(2*2)+(1*6)=139
139 % 10 = 9
So 68253-26-9 is a valid CAS Registry Number.

Electrochemical access to aryl sulfides from aryl thiols and electron-rich arenes with the potassium iodide as a mediator

Liu, Xin,Niu, Pengfei,Jin, Jiali,Shen, Zhenlu,Li, Meichao

, (2019/12/24)

An indirect electrooxidation method catalyzed by potassium iodide at a low potential for the synthesis of aryl sulfides from aryl thiols and electron-rich arenes has been developed. Cyclic voltammetry was carried out to investigate the electrocatalytic ac

Electrocatalytic Oxidant-Free Dehydrogenative C?H/S?H Cross-Coupling

Wang, Pan,Tang, Shan,Huang, Pengfei,Lei, Aiwen

supporting information, p. 3009 - 3013 (2017/03/13)

An environmentally friendly electrocatalytic protocol has been developed for dehydrogenative C?H/S?H cross-coupling. This method enabled C?S bond formation under catalyst- and oxidant-free conditions. Under undivided electrolysis conditions, various aryl/heteroaryl thiols and electron-rich arenes afforded the C?S bond-formation products in 24–99 % yield. A preliminary mechanistic study indicated that the generation of aryl radical cation intermediates is key to the success of this transformation.

Iodine-Mediated Synthesis of Aromatic Thioethers with Aromatic Amines and Sulfonyl Hydrazides in High Regioselectivity via C(sp2)-H Bond Functionalization

Pang, Xiaobo,Xiang, Likui,Yang, Xiaodong,Yan, Rulong

supporting information, p. 321 - 325 (2016/02/14)

An iodine-mediated synthesis of aromatic thioethers from aromatic amines and sulfonyl hydrazides via C(sp2)-H bond functionalization and C-S bond formation has been developed. In this procedure, various substituents on the sulfonyl hydrazides, such as alkyl, methoxyl, chloro, bromo and fluoro groups, and aromatic amines are tolerated in the thiolation which generates the desired products in moderate to good yields.
