Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1260795-42-3, is researched, SMILESS is O=C(C1C(C=O)=CC(Br)=CC=1)OC, Molecular C9H7BrO3Journal, Article, Chemistry – A European Journal called Indium-Catalyzed C-F Bond Transformation through Oxymetalation/β-Fluorine Elimination to Access Fluorinated Isocoumarins, Author is Yata, Tetsuji; Nishimoto, Yoshihiro; Chiba, Kouji; Yasuda, Makoto, the main research direction is difluorovinyl benzoate indium oxymetalation fluorine elimination catalyst; isocoumarin fluorinated preparation; C−F bond transformation; catalysis; fluorinated heterocycles; gem-difluoroalkene; indium.Synthetic Route of C9H7BrO3.

Fluorinated heterocycles have attracted much attention in the pharmaceutical and agrochem. industries. Many strategies have already been developed to achieve the synthesis of fluorinated heterocycles. Formidable challenges remain, however, in the synthesis of fluorinated isocoumarin derivatives that are among the most alluring structural motifs. Herein, the indium-catalyzed C-F bond transformation of 2-(2,2-difluorovinyl) benzoates is reported, which are readily accessible compounds, to give a diverse array of fluorinated isocoumarins, I (R 1 = H, 5-Me, 6-Me, 8-Cl, etc.; R2 = H, n-Bu). The present reaction proceeds smoothly using inexpensive reagents: a catalytic amount of indium salt in the presence of zinc salt. A theor. calculation of potential energy profiles showed that the reaction consists of oxymetalation with the elimination of alkyl halide and the β-fluorine elimination.

Application In Synthesis of Methyl 4-bromo-2-formylbenzoate. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Methyl 4-bromo-2-formylbenzoate, is researched, Molecular C9H7BrO3, CAS is 1260795-42-3, about Highly Enantioselective Synthesis of 2,3-Dihydro-1H-imidazo[2,1-a]isoindol-5(9bH)-ones via Catalytic Asymmetric Intramolecular Cascade Imidization-Nucleophilic Addition-Lactamization.

Highly enantioselective catalytic asym. intramol. cascade imidization-nucleophilic addition-lactamization of N1-alkylethane-1,2-diamine with Me 2-formylbenzoate catalyzed by a chiral phosphoric acid represents the first efficient method for the preparation of medicinally interesting chiral 2,3-dihydro-1H-imidazo[2,1-a]isoindol-5(9bH)-ones, e.g., I, with high yields and excellent enantioselectivities. This strategy has been shown to be quite general toward various Me 2-formylbenzoates.

From this literature《Highly Enantioselective Synthesis of 2,3-Dihydro-1H-imidazo[2,1-a]isoindol-5(9bH)-ones via Catalytic Asymmetric Intramolecular Cascade Imidization-Nucleophilic Addition-Lactamization》,we know some information about this compound(1260795-42-3)Application In Synthesis of Methyl 4-bromo-2-formylbenzoate, but this is not all information, there are many literatures related to this compound(1260795-42-3).

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Covalent bonds immobilization of cofacial Mn porphyrin dimers on an ITO electrode for efficient water oxidation in aqueous solutions, published in 2017-08-31, which mentions a compound: 1260795-42-3, mainly applied to covalent bond immobilization cofacial manganese porphyrin dimer electrocatalyst; ITO electrode water oxidation catalytic oxygen evolution, Electric Literature of C9H7BrO3.

The authors previously reported several Mn porphyrin dimers as the 1st Mn-containing mol. catalysts for H2O oxidation, however, in nonaqueous MeCN solution containing 5% H2O. Here, the authors successfully fabricated these dimers with mono- and hexaphosphonic acid groups, Mn2DP-PO3H2 and Mn2DP-(PO3H2)6, to covalently assemble them on the surface of ITO electrode (ITO = In-doped Sn oxide) and use the Mn2DP-PO3H2 and Mn2DP-(PO3H2)6|ITO assemblies as heterogeneous catalysts for electrochem. H2O oxidation in aqueous buffer solutions The mono-phosphonic acid fabricated assemblies showed unprecedent high turnover frequencies (TOFs) (up to 44.9 s-1) at a low overpotential (η = 0.47 V) in a neutral buffer solution In acidic buffered solutions (pH = 1.5), they showed higher TOFs (up to 47.4 s-1) at a very low overpotential (η = 0.26 V). The robustness of the mono-phosphonic acid fabricated catalysts, Mn2DP-PO3H2|ITO, was tested at a high overpotential (η = 0.80 V). Although they showed an O evolution with 178.3 s-1 TOF, the O evolution completely stopped after 11 h electrolysis. UV-visible spectra monitored during the electrolysis clearly indicated the gradual detachment of the catalysts from the ITO surface is likely the main reason of stopping the O evolution. The hexa-phosphonic acid catalyst assembly, Mn2DP-(PO3H2)6|ITO, however, showed a continuous O evolution without stopping even after 23 h of electrolysis with 199.3 s-1 TOF. Tafel plots in different pHs give insights on the mechanism of H2O oxidation

There is still a lot of research devoted to this compound(SMILES：O=C(C1C(C=O)=CC(Br)=CC=1)OC)Electric Literature of C9H7BrO3, and with the development of science, more effects of this compound(1260795-42-3) can be discovered.
