Methyl 2-bromo-4-fluorobenzoate (cas: 653-92-9) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon–bromine bond is electrophilic in nature. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.HPLC of Formula: 653-92-9

Carbonylative Suzuki-Miyaura couplings of sterically hindered aryl halides: synthesis of 2-aroylbenzoate derivatives was written by Ismael, Aya;Skrydstrup, Troels;Bayer, Annette. And the article was included in Organic & Biomolecular Chemistry in 2020.HPLC of Formula: 653-92-9 This article mentions the following:

A carbonylative approach to the synthesis of diversely substituted 2-aroylbenzoate esters ArC(O)R1 (Ar = 2-methoxyphenyl, thiophen-2-yl, 2-naphthyl, etc.; R1 = 2-methoxycarbonyl-6-methylphenyl, 2-methoxycarbonylphenyl, 2-methoxycarbonyl-4,5-dimethoxyphenyl, etc.) featuring a new protocol for the carbonylative coupling of aryl bromides R1Br with boronic acids ArB(OH)2 and a new strategy to favor carbonylative over non-carbonylative reactions were developed. Two different synthetic pathways – (i) the alkoxycarbonylation of 2-bromo benzophenones R2C6H4C(O)(2-BrC6H5) (R2 = 2-F, 4-F, 3-OMe, 4-OMe) and (ii) the carbonylative Suzuki-Miyaura coupling of 2-bromobenzoate esters – were evaluated. The latter approach provided a broader substrate tolerance, and thus it was the preferred pathway. Here observed that 2-substituted aryl bromides were challenging substrates for carbonylative chem. favoring the non-carbonylative pathway. However, it is found that carbonylative Suzuki-Miyaura couplings can be improved by slow addition of the boronic acid, suppressing the unwanted direct Suzuki coupling and, thus increasing the yield of the carbonylative reaction. In the experiment, the researchers used many compounds, for example, Methyl 2-bromo-4-fluorobenzoate (cas: 653-92-9HPLC of Formula: 653-92-9).
