5700-44-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5700-44-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,0 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5700-44:
(6*5)+(5*7)+(4*0)+(3*0)+(2*4)+(1*4)=77
77 % 10 = 7
So 5700-44-7 is a valid CAS Registry Number.

Electrochemical fluorosulfonylation of alkenes to access vicinal fluorinated sulfones derivatives

Zhao, Bin,Pan, Zichen,Zhu, Anqiao,Yue, Yanni,Ma, Mengtao,Xue, Fei

supporting information, (2022/01/24)

Herein, we report a practical and efficient fluorosulfonylation of the various alkenes with sulfonyl radical sources (RSO2NHNH2) and Et3N·3HF as cost-effective fluorination reagents under mild conditions. Remarkably, this

Photoinduced Hydroarylation and Cyclization of Alkenes with Luminescent Platinum(II) Complexes

Cheng, Hanchao,Lam, Tsz-Lung,Liu, Yungen,Tang, Zhou,Che, Chi-Ming

supporting information, p. 1383 - 1389 (2020/11/30)

Photoinduced hydroarylation of alkenes is an appealing synthetic strategy for arene functionalization. Herein, we demonstrated that aryl radicals generated from electron-deficient aryl chlorides/bromides could be trapped by an array of terminal/internal aryl alkenes in the presence of [Pt(O^N^C^N)] under visible-light (410 nm) irradiation, affording anti-Markovnikov hydroarylated compounds in up to 95 % yield. Besides, a protocol for [Pt(O^N^C^N)]-catalyzed intramolecular photocyclization of acrylanilides to give structurally diverse 3,4-dihydroquinolinones has been developed.

Electrochemical fluorosulfonylation of styrenes

Jiang, Yi-Min,Yu, Yi,Wu, Shao-Fen,Yan, Hong,Yuan, Yaofeng,Ye, Ke-Yin

supporting information, p. 11481 - 11484 (2021/11/16)

An environmentally friendly and efficient electrochemical fluorosulfonylation of styrenes has been developed. With the use of sulfonylhydrazides and triethylamine trihydrofluoride, a diverse array of β-fluorosulfones could be readily obtained. This reaction features mild conditions and a broad substrate scope, which could also be conveniently extended to a gram-scale preparation.
