Author is Dreher, Spencer D.; Krska, Shane W..

A review with new data. The synthetic chem. literature traditionally reports the scope of new methods using simple, nonstandardized test mols. that have uncertain relevance in applied synthesis. In addition, published examples heavily favor pos. reaction outcomes, and failure is rarely documented. In this environment, synthetic practitioners have inadequate information to know whether any given method is suitable for the task at hand. Moreover, the incomplete nature of published data makes it poorly suited for the creation of predictive reactivity models via machine learning approaches. In 2016, we reported the concept of chem. informer libraries as standardized sets of medium- to high-complexity substrates with relevance to pharmaceutical synthesis as demonstrated using a multidimensional principle component anal. (PCA) comparison to the physicochem. properties of marketed drugs. We showed how informer libraries could be used to evaluate leading synthetic methods with the complete capture of success and failure and how this knowledge could lead to improved reaction conditions with a broader scope with respect to relevant applications. In this Account, we describe the progress made and lessons learned in subsequent studies using informer libraries to profile eight addnl. reaction classes. Examining broad trends across multiple types of bond disconnections against a standardized chem. “”measuring stick”” has enabled comparisons of the relative potential of different methods for applications in complex synthesis and has identified opportunities for further development. Furthermore, the powerful combination of informer libraries and 1536-well-plate nanoscale reaction screening has allowed the parallel evaluation of scores of synthetic methods in the same experiment and as such illuminated an important role for informers as part of a larger data generation work-flow for predictive reactivity modeling. Using informer libraries as problem-dense, strong filters has allowed broad sets of reaction conditions to be narrowed down to those that display the highest tolerance to complex substrates. These best conditions can then be used to survey broad swaths of substrate space using nanoscale chem. approaches. Our experiences and those of our collaborators from several academic laboratories applying informer libraries in these contexts have helped us identify several areas for potential improvements to the approach that would increase their ease of use, utility in generating interpretable results, and resulting uptake by the broader community. As we continue to evolve the informer library concept, we believe it will play an ever-increasing role in the future of the democratization of high-throughput experimentation and data science-driven synthetic method development.

The Henry’s law constant defines the solubility of a gas in a liquid solution In this study, a new method for measuring the Henry’s law constant is described. This new colorimetric method is suited for gases which react with water to form acidic or basic solutions when they dissolve, and makes use of measuring the concentration of two forms of a colorimetric pH indicator. By measuring the concentration of the protonated and deprotonated forms of the indicator with UV-visible absorption spectroscopy, the concentration of the hydronium in solution was determined After determining the hydronium concentration, the equilibrium expression for the dissolved gas reacting with water was solved to determine the concentration of the dissolved gas. The concentration of the dissolved gas and the measured partial pressure of the dissolved gas at equilibrium were then used to calculate the Henry’s law constant for the gas. The efficacy of the method is demonstrated by measuring the Henry’s law constant for carbon dioxide in water over a range of pressures (0.680 – 5.10 atm). The results obtained with this method are comparable to the value for the Henry’s law constant that have been previously reported via more traditional methods, and yielded values for the Henry’s law constant for carbon dioxide that ranged from 3.45 x 10-2 to 3.99 x 10-2 M atm-1.

Author is Williamson, J. Charles.

The lever rule applies to any two-component system existing in a state of two-phase equilibrium Here, several classroom demonstrations are described to help students understand liquid-liquid coexistence and the lever rule using a set of isobutyric acid + water + dye samples ranging in composition from water + dye to isobutyric acid + dye. The critical temperature of the partially miscible isobutyric acid + water system is just above room temperature, so students can perceive the general shape of the coexistence curve by watching a progression of phase separations take place over time as the set of prewarmed single-phase samples are allowed to cool. Qual. visualization of the lever rule is demonstrated by showing students the set of samples after equilibration at a temperature well below the critical temperature An interactive Excel spreadsheet is provided to help students connect their observations of the samples with the phase diagram. Quant. and intuitive interpretation of the lever rule can be achieved through height measurements of the biphasic sample layers, leading to immediate graphical determination of the compositions of the isothermal equilibrated phases in the classroom. The set of samples may also be used in an extended classroom or laboratory project to map out the coexistence curve, and advanced students can use the coexistence data to estimate the critical composition of the system, as well as the universal critical exponent β. Finally, preparation of a stable hexaphasic immiscible liquid mixture is described.

Keywords: copper exchanged zeolite HY enantioselective heterogeneous catalysis; aziridination alkene copper exchanged zeolite HY catalysis.They researched the compound: Bis((S)-4-phenyl-4,5-dihydrooxazol-2-yl)methane( cas:132098-59-0 ).Recommanded Product: 132098-59-0. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:132098-59-0) here.

An enantioselective heterogeneous aziridination catalyst is described which is based upon an approach in which cations are anchored by ion-exchange within a microporous or a mesoporous material. The cations can be modified using chiral ligands to form an enantioselective catalyst that is wholly heterogeneous and can be readily reused. Using this approach it is shown that copper-exchanged zeolite HY is a highly active catalyst for the aziridination of alkenes. Modification using bis(oxazolidines) leads to the formation of an enantioselective aziridination catalyst.
