1,2-Dibromobenzene (o-dibromobenzene) is an aryl bromide and isomer of dibromobenzene. It is one of three isomers, the others being 1,3- and 1,4-dibromobenzene. It is a colorless liquid, although impure samples appear yellowish. The compound is a precursor to many 1,2-disubstituted derivatives of benzene.
2 and triphenylphosphine (PPh 3 ), tetrabutylammonium iodide (TBAI) as a phase-transfer catalyst , and sodium hydroxide as a base. Below is an example reaction of 1,3-dibromobenzene to isophthalic acid .
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
1,3-Dibromobenzene has been used as a starting material in the synthesis of antiviral Lufotrelvir, in human clinical trials for the treatment of COVID-19. [3] The first step is formylation of 1,3-dibromobenzene to 2,6-dibromobenzaldehyde, by lithiation with lithium diisopropylamide in THF , followed by quenching with dimethylformamide .
[12] Bildung eines 1,4-Monoarins aus 1,2,4,5-Tetrabrombenzol. When 2,5-dialkylfurans (e.g. 2,5- (di-n-octyl)furan) are used, the dibrominated monoendoxide is formed in 64% yield, from which dibromo-5,8-di-n-octylnaphthalene is formed with zink powder/titanium tetrachloride in 88% yield.
