32884-74-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 32884-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,8,8 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 32884-74:
(7*3)+(6*2)+(5*8)+(4*8)+(3*4)+(2*7)+(1*4)=135
135 % 10 = 5
So 32884-74-5 is a valid CAS Registry Number.

Synergistic Effect of Squaric Acid in Bromine-Catalyzed Deoxygenation of Sulfonyl Derivatives: Mechanistic Investigations and Synthetic Applications in Electrophilic (Fluoroalkyl)sulfenylation

Xiang, Haonan,Liu, Jie,Wang, Jieping,Jiang, Lvqi,Yi, Wenbin

supporting information, p. 181 - 185 (2021/12/17)

A method for electrophilic (fluoroalkyl)sulfenylation of nucleophiles by collaborative CTAB- and squaric acid-promoted deoxygenation of sulfonyl derivatives is reported. Mechanistic studies indicate that squaric acid dramatically decreased the energy barr

Palladium-Catalyzed Direct C2-Biarylation of Indoles

Murugesan, Tamilarasu,Sivarajan, Chinraj,Jayakumari, Chithra Mohan,Singh, Rajat Kumar,Vennapusa, Sivaranjana Reddy,Kaliyamoorthy, Alagiri

supporting information, p. 10838 - 10851 (2021/08/16)

Biaryl and indole units are important structural motifs in several bioactive molecules and functional materials. We have accomplished straightforward access to C2-biarylated indole derivatives through palladium-catalyzed C-H activation strategy with a bro

Recyclable Cellulose-Derived Fe3O4@Pd NPs for Highly Selective C–S Formation by Heterogeneously C–H Sulfenylation of Indoles

Li, Shengyi,Wang, Jinguo,Jin, Jianzhong,Tong, Jianying,Shen, Chao

, p. 2409 - 2414 (2020/02/25)

Abstract: An efficient and convenient method was developed for the preparation of 3-sulfenylindoles via a cellulose-derived Fe3O4@Pd NPs catalyzed heterogeneously C–H sulfenylation of indoles. This approach provides an effective synthetic route to an important class of indoles derivatives and features high efficiency, easy operation, good practicality, and environmental friendliness. The recoverable catalyst was separated from the reaction mixture using an outside magnetic field and can be recycled five times without huge loss of catalytic performance. Graphic Abstract: An efficient method was developed for the preparation of 3-sulfenylindoles via cellulose-derived Fe3O4@Pd NPs catalyzed heterogeneously C–H sulfenylation of indoles.[Figure not available: see fulltext.].
