Exempel på hur man kan använda BROMOBENZENE i en mening

• In the laboratory it can be prepared by the dehydration of benzamide or benzaldehyde oxime or by the Rosenmund–von Braun reaction using cuprous cyanide or NaCN/DMSO and bromobenzene.
• Bromobenzene is an aryl bromide and the simplest of the bromobenzenes, consisting of a benzene ring substituted with one bromine atom.
• In experiment one 2-phenylpropionaldehyde (1, racemic but (R)-enantiomer shown) was reacted with the Grignard reagent of bromobenzene to 1,2-diphenyl-1-propanol (2) as a mixture of diastereomers, predominantly the threo isomer (see for explanation the Fischer projection).
• Since the C–I bond is weaker than C–Br or C–Cl, iodobenzene is more reactive than bromobenzene or chlorobenzene.
• His seminal discoveries in this area ranged from tetracyanoethylene oxide, which adds to olefins through its carbon-carbon bond; hexacyanobutadiene, with an oxidation potential near that of bromine; pentacyanocyclopentadiene, an acid as strong as perchloric acid; diiminosuccinonitrile, a remarkable adduct of cyanogen and hydrogen cyanide; and diazodicyanoimidazole, which cleaves to a carbene that forms a bromo ylide with bromobenzene.
• It results from treating phenylmercury acetate with sodium stannite, by the reaction of mercuric halides with phenylmagnesium bromide, and the reaction of bromobenzene with sodium amalgam.
• Analysis of the rats' excreta revealed the presence of various metabolites, including unchanged HBB, penta bromobenzene, as well as oxygen- and sulfur-containing compounds.
• Tetraphenylphosphonium tetrabromonickelate(II) can be made from nickel bromide, triphenylphosphine, and bromobenzene by heating them together in a sealed tube at 250 °C.
• However the pentaphenylphosphorus reaction with triphenylbismuth difluoride, chloride or bromide makes triphenylbismuth and fluorobenzene, chlorobenzene or bromobenzene.
