33597-89-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33597-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,5,9 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33597-89:
(7*3)+(6*3)+(5*5)+(4*9)+(3*7)+(2*8)+(1*9)=146
146 % 10 = 6
So 33597-89-6 is a valid CAS Registry Number.

Deoxygenation of sulphoxides to sulphides with trichlorophosphane

Zhao, Xia,Zheng, Xiancai,Yang, Bo,Sheng, Jianqiao,Lu, Kui

, p. 1200 - 1204 (2018)

An efficient route to deoxygenation of sulphoxides to sulphides with PCl3 under mild reaction condition was developed. PCl3 was used as a reducing agent for the first time to convert sulphoxides to sulphides. The mild conditions, use of cheap and readily available reagent, and broad substrate scope render it a useful strategy for preparing sulphides.

Synthesis method of thioether compounds

-

Paragraph 0087-0091, (2019/08/02)

The invention discloses a synthesis method of thioether compounds. The method comprises steps as follows: phosphorus trichloride and a solvent with uniformly distributed sulfoxide compounds are mixeduniformly, after mixing, the mixture is subjected to a reaction at the temperature of 20-25 DEG C for 0.5-6 h, and the thioether compounds are obtained, wherein the solvent is acetonitrile. Compared with the prior art, the synthesis method has the advantages that raw materials are cheap and easy to obtain, a reducer is cheap and easy to obtain and store, and a series of thioether compounds can beobtained.

Regioselective synthesis and antimicrobial evaluation of some thioether–amide linked 1,4-disubstituted 1,2,3-triazoles

Kaushik,Pahwa, Ashima,Thakur, Rajesh,Kaur, Pawan

supporting information, p. 368 - 378 (2017/02/10)

A series of 1,4-disubstituted 1,2,3-triazoles having thioether as well as amide linkage were synthesized from aryl(prop-2-yn-1-yl)sulfanes and 2-azido-N-substituted acetamides through Cu(I) catalyzed click reaction. Structures of newly synthesized compounds (3a–3x) were confirmed by spectral techniques like FTIR,1H NMR,13C NMR, and HRMS. The synthesized triazoles were evaluated for in vitro antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, Candida albicans, and Aspergillus niger. Compounds 3m and 3q displayed appreciable broad spectrum antimicrobial activity against tested microbial strains. The nanoformulations of compounds 3m and 3q were also prepared and examined against one bacterial strain and one fungal strain.
