Milic, Mira;Targos, Karina;Tellez Chavez, Magda;Thompson, Madison A. M.;Jennings, Julia J.;Franz, Annaliese K. research published 《 NMR Quantification of Hydrogen-Bond-Accepting Ability for Organic Molecules》, the research content is summarized as follows. The hydrogen-bond-accepting abilities for more than 100 organic mols. are quantified using 19F and 31P NMR spectroscopy with pentafluorobenzoic acid (PFBA) and phenylphosphinic acid (PPA) as com. available, inexpensive probes. Anal. of pyridines and anilines with a variety of electronic modifications demonstrates that changes in NMR shifts can predict the secondary effects that contribute to H-bond-accepting ability, establishing the ability of PFBA and PPA binding to predict electronic trends. The H-bond-accepting abilities of various metal-chelating ligands and organocatalysts are also quantified. The measured Δδ(31P) and Δδp(19F) values correlate strongly with Hammett parameters, pKa of the protonated HBA, and proton-transfer basicity (pKBH+).
Recommanded Product: Methyl furan-2-carboxylate, Methyl 2-furoate has been identified as one of the volatile flavor compounds in tequila, okra, berrycactus and black currant juice.
Methyl 2-furoate, also known as fema 2703 or methyl pyromucate, belongs to the class of organic compounds known as furoic acid esters. These are ester derivatives of furoic acid. Methyl 2-furoate is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Within the cell, methyl 2-furoate is primarily located in the cytoplasm. Methyl 2-furoate is a sweet, fruity, and fungal tasting compound that can be found in a number of food items such as cocoa and cocoa products, potato, tamarind, and fruits. This makes methyl 2-furoate a potential biomarker for the consumption of these food products.
Methyl 2-furoate is a reactive compound that belongs to the family of sesquiterpene lactones. It has been shown to have phosphotungstic acid and hydrochloric acid reactivity, as well as nitrous and water vapor sensitivity. Methyl 2-furoate also reacts with radiation, which can be used for structural analysis. The compound is an intermediate in the synthesis of pluronic p123, which is used in fabricating biomedical devices. Methyl 2-furoate has been shown to have anti-inflammatory properties through its inhibitory effect on prostaglandin synthesis., 611-13-2.
