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 .
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 .
Cyclohexylamine is produced by two routes, the main one being the complete hydrogenation of aniline using some cobalt- or nickel-based catalysts: [4] C 6 H 5 NH 2 + 3 H 2 → C 6 H 11 NH 2 It is also prepared by alkylation of ammonia using cyclohexanol .
Benzyl bromide is used in organic synthesis for the introduction of the benzyl groups when the less expensive benzyl chloride is insufficiently reactive. [6] [7] Benzylations are often achieved in the presence of catalytic amounts of sodium iodide, which generates the more reactive benzyl iodide in situ. [3]
para-Quaterphenyl, or p-quaterphenyl, is a chemical compound consisting of a straight chain of four phenyl groups connected in the para position. It can be considered as next in the series of benzene, biphenyl, para-terphenyl.
A mixture of cis-decalin and CXB can simultaneously match optical index and density of PMMA. [1] 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 ]
Cyclohexylacetone along with N-methylformamide can be used to make racemic propylhexedrine in a similar fashion to the phenylacetone synthesis of methamphetamine. [1] Another cyclohexylacetone use is in the production of droprenilamine .
