123726-16-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123726-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,2 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 123726-16:
(8*1)+(7*2)+(6*3)+(5*7)+(4*2)+(3*6)+(2*1)+(1*6)=109
109 % 10 = 9
So 123726-16-9 is a valid CAS Registry Number.

Copper-catalyzed arylation of polycyclic aromatic hydrocarbons by the PO group

Niu, Yuan,Qi, Zhichao,Lou, Qinxin,Bai, Pengbo,Yang, Shangdong

, p. 14721 - 14724 (2020)

The first example of a directed and regioselective arylation of polycyclic aromatic hydrocarbons (PAHs) by using a PO directing group is reported herein. The protocol uses a cheap copper catalyst, and results in a breakthrough meta-selective C-H functionalization of arylphosphine oxide compounds. Substrates with potential fluorescence properties, for example, pyrene and fluoranthene, were successfully arylated under the system, thus achieving an efficient modification of fluorescent molecules containing the PO functional group. This journal is

N1- and N3-Arylations of Hydantoins Employing Diaryliodonium Salts via Copper(I) Catalysis at Room Temperature

Abha Saikia, Raktim,Barman, Dhiraj,Dutta, Anurag,Jyoti Thakur, Ashim

supporting information, p. 400 - 410 (2020/12/17)

Copper(I)-catalyzed N-arylation (both N1- and N3-) of hydantoins with diaryliodonium salts as aryl partners at room temperature is reported. The transformation allows diverse scopes on both hydantoins and diaryliodonium salts deliver

Direct Copper-Catalyzed C-3 Arylation of Diphenylphosphine Oxide Indoles

Huang, Xiao-Ling,Li, Chong,Wang, Juan,Yang, Shang-Dong

supporting information, (2021/10/25)

We have developed a simple and effective method for the C-3 arylation of phosphorus-containing indole compounds in the presence of CuI under mild conditions. This reaction provides a reliable method for the modification of ligands.
