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]
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 .
Due to the moderate dielectric constant of CXB (ε = 7.9 [2]), PMMA acquires charges that can be screened by the addition of salt (e.g. tetrabutyl ammonium bromide), leading to a very good approximation of colloidal hard sphere. [3]
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]
[3] Bromobenzene is used to introduce a phenyl group into other compounds. One method involves its conversion to the Grignard reagent, phenylmagnesium bromide. 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.

4-Bromophenylacetic acid may be prepared by the addition of a bromine atom to phenylacetic acid through electrophilic aromatic substitution.It was first prepared in the laboratory by treatment of phenylacetic acid with bromine and mercuric oxide; a mixture of the 2- and 4- isomers is made, and the 4- isomer is isolated by fractional crystallization.
