General Description

2-Bromo-2'-Chlorobiphenyl is a specific type of biphenyl that is organobromine and organochlorine in nature. It's chemical formula is C12H8BrCl. Structurally this compound can be described as a biphenyl molecule in which one hydrogen atom on each of the phenyl rings is replaced by bromine and chlorine respectively. This chemical compound falls under the group of polybrominated biphenyls (PBBs) and polychlorinated biphenyls (PCBs) which are known to exhibit a broad range of toxic effects. In terms of environmental science, these are often recognized as persistent organic pollutants due to their stability and resistance to degradation and are thus a concern for environmental health. They are mostly synthesized for use in various industrial applications as flame retardants and dielectric fluids in transformers among others.

Check Digit Verification of cas no

The CAS Registry Mumber 107208-70-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,2,0 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 107208-70:
(8*1)+(7*0)+(6*7)+(5*2)+(4*0)+(3*8)+(2*7)+(1*0)=98
98 % 10 = 8
So 107208-70-8 is a valid CAS Registry Number.

Synthesis and Structure of a Propeller-Shaped Polycyclic Aromatic Hydrocarbon Containing Seven-Membered Rings

Kawai, Kazuya,Kato, Kenta,Peng, Lingqing,Segawa, Yasutomo,Scott, Lawrence T.,Itami, Kenichiro

, p. 1932 - 1935 (2018)

The synthesis and structure of a C3-symmetric propeller-shaped polycyclic aromatic hydrocarbon that bears three seven-membered rings is reported. The synthesis was accomplished in three steps from benzo[c]naphtho[2,1-p]chrysene, including a Pd-catalyzed intramolecular C-H arylation for the formation of the seven-membered rings. The combination of the helicities (P/M) of the three seven-membered-ring moieties and three [4]helicene moieties affords 24 possible conformers, and two relatively stable conformations were observed by 1H NMR spectroscopy.

A site-selective and stereospecific cascade Suzuki-Miyaura annulation of alkyl 1,2-bisboronic esters and 2,2′-dihalo 1,1′-biaryls

Willems, Suzanne,Toupalas, Georgios,Reisenbauer, Julia C.,Morandi, Bill

supporting information, p. 3909 - 3912 (2021/04/26)

A cascade Suzuki-Miyaura cross-coupling giving rise to 9,10-dihydrophenanthrenes has been developed. Using biaryls with unsymmetrical substitution-pattern full site-selectivity was observed. Furthermore, this cross-coupling of an alkyl 1,2-bisboronic pinacol ester proceeds through the challenging coupling of a secondary boronate with complete stereoretention.

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.
