4-Bromobenzaldehyde, or p-bromobenzaldehyde, is an organobromine compound with the formula BrC 6 H 4 CHO. It is one of three isomers of bromobenzaldehyde . [ 3 ] It displays reactivity characteristic of benzaldehyde and an aryl bromide .
Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.
Benzamide is an organic compound with the chemical formula of C 7 H 7 NO.It is the simplest amide derivative of benzoic acid.In powdered form, it appears as a white solid, while in crystalline form, it appears as colourless crystals. [5]
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 .
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]
