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 .
Methyl benzoate is an organic compound. It is an ester with the chemical formula C 6 H 5 COOCH 3, sometimes abbreviated as PhCO 2 Me, where Ph and Me are phenyl and methyl, respectively. Its structure is C 6 H 5 −C(=O)−O−CH 3. It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents.
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
Methyl 4-bromophenylacetate is made from 4-bromophenylacetic acid by Fischer esterification, refluxing it with methanol acidified with sulfuric acid. [3] An ethyl ester can be made in an analogous way using ethanol instead of methanol. [4] A hydrazone derivative, 2-(4-bromophenyl)acetohydrazide, is made by refluxing the methyl ester with ...
Methyl 4-iodobenzoate, or methyl p-iodobenzoate, is an organic compound with the formula IC 6 H 4 COOCH 3. [3] It is the methyl ester of 4-iodobenzoic acid , or may also be viewed as an iodinated derivative of methyl benzoate .
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]
Volcafe, a top coffee trader, cut its 2025-2026 production outlook by nearly 25% to 34.4 million bags of Arabica beans on Tuesday, according to Bloomberg. This marks the fifth consecutive year of ...
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 .
