Benzyl bromide is an organic compound with the formula C 6 H 5 CH 2 Br. The molecule consists of a benzene ring substituted with a bromomethyl group. It is a colorless liquid with lachrymatory properties. The compound is a reagent for introducing benzyl groups. [3] [4]
Fluorobenzene is an aryl fluoride and the simplest of the fluorobenzenes, with the formula C 6 H 5 F, often abbreviated PhF. A colorless liquid, it is a precursor to many fluorophenyl compounds. A colorless liquid, it is a precursor to many fluorophenyl compounds.
This reagent can be used, e.g. in the reaction with carbon dioxide to prepare benzoic acid. [4] Other methods involve palladium-catalyzed coupling reactions, such as the Suzuki reaction. Bromobenzene is used as a precursor in the manufacture of phencyclidine.
4-Fluorobromobenzene is synthesized via bromination of fluorobenzene in the presence of a Lewis acid catalyst such as iron(III) bromide or aluminium tribromide. [2]4-Bromofluorobenzene is regarded by the Toxic Substances Control Act as a high production volume chemical, that is, a chemical that 1 million pounds (about 500 tonnes) per year is either produced in or imported to the United States.
The bromochloromethane product from either reaction can further react in a similar manner: 6 CH 2 BrCl + 3 Br 2 + 2 Al → 6 CH 2 Br 2 + 2 AlCl 3 CH 2 BrCl + HBr → CH 2 Br 2 + HCl. In the laboratory, it is prepared from bromoform using sodium arsenite and sodium hydroxide: [4] CHBr 3 + Na 3 AsO 3 + NaOH → CH 2 Br 2 + Na 3 AsO 4 + NaBr

184.5 °c (364.1 °f; 457.7 k) Benzyl bromide is an isomer, which has a bromine substituted for one of the hydrogens of toluene 's methyl group, and it is sometimes named α-bromotoluene. Preparation
Most primary and secondary perfluoroalcohols are unstable, for example trifluoromethanol eliminates hydrogen fluoride, forming carbonyl fluoride. [2] This reaction is reversible. [3] CF 3 OH → COF 2 + HF. Stable perfluorinated alcohols include nonafluoro-tert-butyl alcohol ((CF 3) 3 COH) and pentafluorophenol (C 6 F 5 OH).
