Verwenden
Methyl 4-bromobenzoate is a halogenated benzoate used as a reagent in organic synthesis. It can be used to stimulate microbial dechlorination of PCBs. By condensing methyl 4-bromobenzoate with 3-buten-1-ol, 4-(4-methylphenyl)butanal can be obtained.
Application
Methyl 4-bromobenzoate may be used in the following syntheses:
1. Methyl 4-(2-pyridyl)benzoate by cross coupling reaction with lithium 2-pyridyltriolborate.
2. Methyl 4-imidazo[1,2-a]pyridin-3-ylbenzoate by ligand-free Pd(OAc)2 catalyzed reaction with Imidazo[1,2-a]pyridine.
3. Methyl (E)-4-[3-(2-methoxycarbonylvinyl)-thiophen-2-yl]acrylate by reacting with methyl (E)-3-(thiophen-3-y)lacrylate.
Verwenden
Methyl 4-bromobenzoate is used as a starting material in the synthesis of three-carbon-bridged 5-substituted furo[2,3-d]pyrimidine and 6-substituted pyrrolo[2,3-d]pyrimidine and methyl 4-tri-n-butylstannylbenzoate. It is also used to stimulate microbial dechlorination of polychlorinated biphenyls. Further, it is used in the preparation of stable radioiodinating reagent to label monoclonal antibodies for radiotherapy of cancer.
Allgemeine Beschreibung
Methyl 4-bromobenzoate is a para-substituted aryl bromide. Mol-ecules of methyl 4-bromobenzoate are almost planar. The compound is isostructural with methyl 4-iodo-benzoate. The Zeeman effect on the N.Q.R. (nuclear quadrupole resonance) of methyl 4-bromobenzoate on single crystals, has been investigated by the ′geometric method′.
läuterung methode
Crystallise the ester from MeOH. EtOH (m 81o, also 80.5o, 79.5o) or *C6H6/pet ether (m 78-79o). [Beilstein 9 H 352, 9 III 1405, 9 IV 1017.]
