15563-45-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 15563-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,6 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 15563-45:
(7*1)+(6*5)+(5*5)+(4*6)+(3*3)+(2*4)+(1*5)=108
108 % 10 = 8
So 15563-45-8 is a valid CAS Registry Number.

Cobalt(iii)-catalyzed C-H amidation of: N, N -dialkyl thiobenzamides by sulfur coordination

Gao, Pengpeng,Zhang, Xiaohui,Zheng, Qing-Zhong

supporting information, p. 10332 - 10336 (2021/12/17)

An efficient inexpensive cobalt(iii)-catalyzed intermolecular amidation of N,N-dialkyl thiobenzamides with 1,4,2-dioxazol-5-ones via C-H bond activation is described. The reaction proceeds with high functional group tolerance under external oxidant free conditions, providing a straightforward approach for the direct modification of thioamide derivatives, which are prevalent organic motifs found in vital biological and pharmaceutical molecules.

PHOTOCATALYTIC SYSTEM AND APPLICATIONS THEREOF

-

Page/Page column 35; 36, (2019/05/15)

The present invention relates to novel poly(heptazine imides), a photocatalytic system comprising such poly(heptazine imides) and a sulfur source as well as the application thereof in photocatalytic reactions.

Sulfur-Catalyzed Oxidative Coupling of Dibenzyl Disulfides with Amines: Access to Thioamides and Aza Heterocycles

Nguyen, Thanh Binh,Nguyen, Le Phuong Anh,Nguyen, Thi Thu Tram

supporting information, p. 1787 - 1791 (2019/02/26)

In the presence of catalytic amounts of elemental sulfur, dibenzyl disulfide/DMSO was found to be an excellent thiobenzoylating agent of amines to provide a wide range of thioamides. The reaction becomes autocatalytic when anilines substituted by an o-cyclizable group were used as nucleophile, leading to the corresponding 2-aryl aza heterocycles. (Figure presented.).
