17135-74-9 Usage

General Description

1,8-Dibromonaphtalene is a chemical compound with the molecular formula C10H6Br2. 1,8-Dibromonaphtalene is a naphthalene derivative in which the 1 and 8 positions of the naphthalene structure are substituted by bromine atoms. Its chemical properties are signified by its aromatic nature and the presence of two bromine substituents, which make it effective in various chemical reactions, particularly ones involving substitutions or coupling. 1,8-Dibromonaphtalene is typically used in organic chemistry research and synthesis due to its high reactivity and ability to act as a precursor for other compounds. However, like many brominated substances, it must be handled with care as it may pose health risks.

Check Digit Verification of cas no

The CAS Registry Mumber 17135-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,3 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 17135-74:
99 % 10 = 9
So 17135-74-9 is a valid CAS Registry Number.

Facile Route to Quadruply Annulated Borepins

Schickedanz, Kai,Radtke, Julian,Bolte, Michael,Lerner, Hans-Wolfram,Wagner, Matthias

, p. 2842 - 2851 (2017)

A two-step synthesis sequence furnishes quadruply annulated borepins in high yields. The first step involves a nucleophilic substitution reaction between aryl-BF3K salts (aryl = mesityl, phenyl) and lithiated bromonapthalene derivatives LiNaphBr,R (HNaphBr,R = 8-bromonaphthalene (a), 5-bromoacenaphthene (b), 5-bromoacenaphthylene (c)). In the second step, the resulting heteroleptic triarylboranes aryl-B(NaphBr,R)2 (3a-c) are subjected to an intramolecular Ni-mediated Yamamoto reaction to close the seven-membered rings and create the borepins 4a-c. Only in the case of 3b is the Yamamoto reaction accompanied by a C-H activation reaction furnishing the 7-hydro-7-borabenzo[de]anthracene derivative 5. The product ratio 4b/5 can be influenced by control of the local Ni(0) concentration. The borepins 4a-c are benchtop stable and highly soluble even in hexane. Compounds 4a-c undergo reversible one-electron reduction; 4c is also able to accept a second electron in a reversible manner and already at moderate potential values (E1/2 = ?1.49 V and ?1.84 V (vs FcH/FcH+)). 4a, 4b, and 5 show photoluminescence in the blue-green region of the spectrum, while 4c is nonfluorescent, which is likely attributable to an intramolecular charge-transfer transition.

Synthesis of 1,2-disubstituted acenaphthylenes by palladium-catalyzed annulation reactions of dibromoarenes with internal alkynes

An, Wenbo,Li, Gaoqiang,Ma, Jun,Tian, Youping,Xu, Feng

supporting information, p. 1585 - 1590 (2014/07/08)

A simple and versatile route to 1,2-disubstituted acenaphthylenes has been developed. The method involves palladium-catalyzed annulation of 1,8-dibromonaphthalene or 5,6-dibromoacenaphthylene with an internal alkyne, and does not require any organometallic reagent. A range of 1,2-disubstituted acenaphthylenes and 5,6-disubstituted 1,2-dihydrocyclopenta[f,g]acenaphthylenes were prepared in moderate to good yields. The method provides a rapid and simple route to dibenzo[j,l]fluoranthene through an Ullmann coupling. Georg Thieme Verlag Stuttgart New York.
