65227-54-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65227-54-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,2,2 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 65227-54:
(7*6)+(6*5)+(5*2)+(4*2)+(3*7)+(2*5)+(1*4)=125
125 % 10 = 5
So 65227-54-5 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

Dual Roles of Rongalite: Reductive Coupling Reaction to Construct Thiosulfonates Using Sulfonyl Hydrazides

Zhang, Guofu,Fan, Qiankun,Zhao, Yiyong,Wang, Huimin,Ding, Chengrong

supporting information, p. 81 - 85 (2020/11/03)

A tunable and practical transformation of structurally diverse sulfonyl hydrazides into thiosulfonates in the presence of Rongalite (NaHSO 2·CH 2O) was developed. Transition-metal-free conditions, operational simplicity, and readily available reagents are the striking features of this protocol. It is the first example for the synthesis of thiosulfonates using sulfonyl hydrazides with the assistance of reductant. Additionally, the mechanistic studies revealed that this transformation probably undergoes via a reducing-coupling pathway.

NaHSO3-Mediated Direct Synthesis of Sulfinic Esters from Sulfonyl Hydrazides under Transition-Metal-Free Conditions

Zhang, Guofu,Fan, Qiankun,Wang, Huimin,Zhao, Yiyong,Ding, Chengrong

supporting information, p. 833 - 837 (2020/12/07)

We have developed a protocol for the NaHSO3-promoted esterification of sulfonyl hydrazides with alcohols for the synthesis of sulfinic esters. Various sulfonyl hydrazides could be converted to the corresponding sulfinic esters in good to high yields. The merits of this protocol include mild transition-metal-free reaction conditions, an inexpensive and available reagent, and operational simplicity. Controlled experiments reveal that this transformation probably undergoes via a radical pathway. (Figure presented.).
