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.
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 .
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

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]
For example, nonylmagnesium bromide reacts with methyl p-chlorobenzoate to give p-nonylbenzoic acid, in the presence of Tris(acetylacetonato)iron(III) (Fe(acac) 3), after workup with NaOH to hydrolyze the ester, shown as follows. Without the Fe(acac) 3, the Grignard reagent would attack the ester group over the aryl halide. [21]
Halogenation with thionyl chloride gave 4-Bromo-3,5-dimethoxybenzoyl chloride [56518-43-5] (6). Rosenmund reduction gave 4-Bromo-3,5-dimethoxybenzaldehyde [31558-40-4] (7). {Alternatively DIBAL meant that FGI from ester to aldehyde was accomplished in only 1 step}.
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 .
