General Description

4-Bromo-4'-Methylbiphenyl is a chemical compound with the molecular formula C13H11Br. It is a derivative of biphenyl, containing a bromine atom at the 4-position and a methyl group at the 4'-position. 4-BroMo-4'-Methylbiphenyl is used in organic synthesis as a reagent and intermediate for the production of pharmaceuticals, agrochemicals, and other organic compounds. It is also used in research and development of new materials and chemical processes. 4-Bromo-4'-Methylbiphenyl is a colorless to light yellow liquid at room temperature, and it is classified as a hazardous substance due to its flammability and potential health hazards.

Check Digit Verification of cas no

The CAS Registry Mumber 844856-52-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,8,5 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 844856-52:
(8*8)+(7*4)+(6*4)+(5*8)+(4*5)+(3*6)+(2*5)+(1*2)=206
206 % 10 = 6
So 844856-52-6 is a valid CAS Registry Number.

Palladium (II)–Salan Complexes as Catalysts for Suzuki–Miyaura C–C Cross-Coupling in Water and Air. Effect of the Various Bridging Units within the Diamine Moieties on the Catalytic Performance

Bunda, Szilvia,Joó, Ferenc,Kathó, ágnes,Udvardy, Antal,Voronova, Krisztina

supporting information, (2020/09/18)

Water-soluble salan ligands were synthesized by hydrogenation and subsequent sulfonation of salens (N,N’-bis(slicylidene)ethylenediamine and analogues) with various bridging units (linkers) connecting the nitrogen atoms. Pd (II) complexes were obtained in reactions of sulfosalans and [PdCl4]2?. Characterization of the ligands and complexes included extensive X-ray diffraction studies, too. The Pd (II) complexes proved highly active catalysts of the Suzuki–Miyaura reaction of aryl halides and arylboronic acid derivatives at 80 ?C in water and air. A comparative study of the Pd (II)–sulfosalan catalysts showed that the catalytic activity largely increased with increasing linker length and with increasing steric congestion around the N donor atoms of the ligands; the highest specific activity was 40,000 (mol substrate) (mol catalyst × h)?1. The substrate scope was explored with the use of the two most active catalysts, containing 1,4-butylene and 1,2-diphenylethylene linkers, respectively.

Visible-Light-Promoted, Catalyst-Free Gomberg-Bachmann Reaction: Synthesis of Biaryls

Lee, Juyoung,Hong, Boseok,Lee, Anna

, p. 9297 - 9306 (2019/08/12)

Biaryls were synthesized via a novel visible-light-promoted Gomberg-Bachmann reaction that does not require a photosensitizer or any metal reagents. The formation of an electron donor-acceptor complex between aryl diazonium salts and pyridine allows, under visible-light irradiation, the synthesis of biaryls in moderate-to-high yields.
