Recommanded Product: Methyl 3-phenylpropionate. I found the field of Science & Technology – Other Topics very interesting. Saw the article Taking electrodecarboxylative etherification beyond Hofer-Moest using a radical C-O coupling strategy published in 2020.0, Reprint Addresses Goossen, LJ (corresponding author), Ruhr Univ Bochum, Fak Chem & Biochem, Univ Str 150, D-44801 Bochum, Germany.. The CAS is 103-25-3. Through research, I have a further understanding and discovery of Methyl 3-phenylpropionate.

Established electrodecarboxylative etherification protocols are based on Hofer-Moest-type reaction pathways. An oxidative decarboxylation gives rise to radicals, which are further oxidised to carbocations. This is possible only for benzylic or otherwise stabilised substrates. Here, we report the electrodecarboxylative radical-radical coupling of lithium alkylcarboxylates with 1-hydroxybenzotriazole at platinum electrodes in methanol/pyridine to afford alkyl benzotriazole ethers. The substrate scope of this electrochemical radical coupling extends to primary and secondary alkylcarboxylates. The benzotriazole products easily undergo reductive cleavage to the alcohols. They can also serve as synthetic hubs to access a wide variety of functional groups. This reaction prototype demonstrates that electrodecarboxylative C-O bond formation can be taken beyond the intrinsic substrate limitations of Hofer-Moest mechanisms.

By using 2-fluoro-substituted diaryliodonium salts, a novel benzocylization has been accomplished for the synthesis of 3,4-benzocoumarin derivatives via a cascade of ortho-arylation and defluorination in the presence of palladium catalysts. The reaction exhibits a broad compatibility of readily available aromatic acids with an excellent level of site-selectivity. Mechanistic investigations revealed a unique reactivity of carboxylic acid directed arylation by followed nucleophilic substitution of aromatic fluoride in the present system.

A new triazole-functionalized tetracarboxylic acid ligand (H4L) has been synthesized and utilized for the fabrication of a 3D Zn-II organic framework with a Zn-4(-COO)(6) cluster as the secondary building unit. The framework exhibits very good thermal stability and consists of dual functionalities of exposed Lewis acidic metal sites and accessible nitrogen-donor Lewis basic sites. The Lewis basic nitrogen sites in the framework serve as CO2 binding sites for highly selective CO2 capture and the presence of exposed Lewis acidic metal sites in the framework make it an efficient heterogeneous catalyst for the chemical fixation of CO2 into value-added cyclic carbonates under ambient conditions.

The reactivity of ortho-functionalized N-heterocycle-substituted iodoarenes (NHIAs) as organocatalysts in iodine(I/III)-mediated oxidations was systematically investigated in the alpha-tosyloxylation of ketones as the model reaction. During a systematic catalyst evolution, it was found that NH-triazoles and benzoxazoles have the most significant positive influence on the reactivity of the central iodine atom. A further catalyst improvement which focused on the substitution pattern of the arene revealed a remarkable ortho-effect. By introduction of an o-OMe group we were able to generate a novel NHIA with a so far unseen catalytic efficiency. This new catalyst is not only easy to synthesize but also enabled the alpha-tosyloxylation of carbonyl compounds at the lowest reported catalyst loading of only 1 mol%. Finally, the performance of this iodine(I) catalyst was successfully demonstrated in intramolecular oxidative couplings of biphenyls and oxidative rearrangements.

In order to discover more potent antifungal, a series of 2-aryl-3,4-dihydroisoquinolin-2-iums were reasonable designed and productive synthesized by introducing benzoic acid and phenol pharmacophores into the 2-position of isoquinoline. Their structures were identified by NMR and HRMS. The preliminary in vitro antifungal results showed that most of the title compounds exhibited moderate to significant inhibitory activities against various phytopathogenic fungi at 50 mu g.mL(-1), and were equal to controls (chlorothalonil, carbendazim). The concentration of 50% inhibition rate (EC50]) of 2-(3-ethoxycarbonyl-phenyl)-3,4-dihydroisoquinolin-2-ium (4j) against R. solani was 3.8495 mu g.mL(-1), which was significantly superior to chlorothalonil (4.6328 mu g.mL(-1)). All the EC50 values of 5 compounds (7.4583 similar to 15.4495 mu g.mL(-1)) against R. cerealis were better than chlorothalonil (16.0137 mu g.mL(-1)), and 2-(4-methoxycarbonylphenyl)-3,4-dihydroisoquinolin-2-ium (4f) is the best one. The present results provide valuable information for development of plant-based antifungal agents.

In the presented work, five bio-based and bio-degradable cyclic esters, i.e. lactones, have been investigated as possible phase change materials for applications in latent heat storage systems. Commercial natural lactones such as epsilon-caprolactone and gamma-valerolactone were easily purchased through chemical suppliers, while 1,2-campholide, oxa-adamantanone and dibenzochromen-6-one were synthesized through Baeyer-Villiger oxidation. The compounds were characterized with respect to attenuated total reflectance spectroscopy and gas chromatography coupled with mass spectroscopy, in order to confirm their chemical structures and identity. Subsequently, thermogravimetric analysis and differential scanning calorimetry were used to measure the phase change temperatures, enthalpies of fusion, degradation temperatures, as well to estimate the degree of supercooling. The lactones showed a wide range of phase change temperatures from -40 degrees C to 290 degrees C, making them a high interest for both low and high temperature latent heat storage applications, given the lack of organic phase change materials covering phase change temperature ranges below 0 degrees C and above 80 degrees C. However, low enthalpies of fusion, high degrees of supercooling and thermal degradations at low temperatures were registered for all samples, rendering them unsuitable as phase change materials.

Vicinal diboration of alkyl bromides via tandem catalysis is reported. The reported reaction exhibits a broad substrate scope, good functional group compatibility, and regioselectivity. Moreover, it shows good practicality due to the easy accessibility of alkyl bromides in combination with diverse transformations of diboronates. Mechanism study indicates that terminal alkenes are generated selectively through nickel-catalyzed dehydrohalogenation of alkyl bromides followed by base/MeOH promoted diboration process to provide 1,2-diboration products.
