26547-29-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26547-29-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,5,4 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 26547-29:
(7*2)+(6*6)+(5*5)+(4*4)+(3*7)+(2*2)+(1*9)=125
125 % 10 = 5
So 26547-29-5 is a valid CAS Registry Number.

Copper-free sonogashira coupling reaction using a trans-spanning 1,2-Bis(2-thienylethynyl)benzene ligand

Atobe, Shingo,Sonoda, Motohiro,Suzuki, Yuki,Shinohara, Hiroyuki,Yamamoto, Takuya,Ogawa, Akiya

, p. 980 - 982 (2011)

Novel copper-free Sonogashira coupling reaction of aryl halides with terminal acetylenes proceeded in the presence of 1,2-bis(2-thienylethynyl) benzene (1) as a trans-bidentatable ligand.

Coupling of thiols and aromatic halides promoted by diboron derived super electron donors

Franco, Mario,Vargas, Emily L.,Tortosa, Mariola,Cid

supporting information, p. 11653 - 11656 (2021/11/12)

We have proven that pyridine-boryl complexes can be used as superelectron donors to promote the coupling of thiols and aromatic halides through a SRN1 mechanism. The reaction is efficient for a broad substrate scope, tolerating heterocycles including pyridines, enolizable or reducible functional groups. The method has been applied to intermediates in drug synthesis as well as interesting functionalized polythioethers through a controlled and consecutive intramolecular electron transfer process.

Palladium Nanoparticles Immobilized on Nanosilica Triazine Dendritic Polymer (Pd np -nSTDP) as Catalyst in the Synthesis of Mono-, Di-, and Trisulfides through C-S Cross-Coupling Reactions

Isfahani, Amir Landarani,Mohammadpoor-Baltork, Iraj,Mirkhani, Valiollah,Moghadam, Majid,Khosropour, Ahmad Reza,Tangestaninejad, Shahram,Nasr-Esfahani, Mahboobeh,Rudbari, Hadi Amiri

supporting information, p. 645 - 652 (2014/04/03)

A wide variety of diaryl sulfides has been synthesized in excellent yields via C-S cross-couplings of aryl/heteroaryl halides with aromatic/heteroaromatic thiols in the presence of palladium nanoparticles immobilized on nanosilica triazine dendritic polymer (Pd np -nSTDP) as a reusable catalyst under thermal conditions and microwave irradiation. Pd np -nSTDP also showed excellent catalytic activity for the preparation of a series of di- and trisulfides with benzene, pyridine, pyrimidine, and/or 1,3,5-triazine as the central cores by one-pot multi C-S cross-coupling reactions.
