Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 15679-12-6, Name is 2-Ethyl-4-methylthiazole, 15679-12-6.

Aryl triflates were found to be suitable partners for the palladium catalyzed direct arylation of heteroaromatics via C-H activation- functionalization. The reaction conditions and the catalyst have a determining influence on the yields. The system combining PPh3 and Pd(OAc) 2 using KOAc as base and DMF as solvent promotes the selective 2- or 5-arylations in moderate to high yields. Several heteroaromatics such as furan, thiophene, thiazole or oxazole derivatives have been employed successfully. The electronic properties of the aryl triflates also have a decisive influence on the yields of the coupling products. Electron-rich aryl triflates gave satisfactory results, whereas the electron-poor ones led to the formation of phenols. The Royal Society of Chemistry 2008.

Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 18640-74-9, C7H11NS. A document type is Conference Paper, introducing its new discovery., 18640-74-9

An empirical model was developed to describe and predict the change in gas-liquid partition behaviour of a wide range of volatile compounds in aqueous sucrose solutions. The static equilibrium headspace concentrations of 40 volatiles (from different chemical classes e.g. pyrazines, alcohols, esters and ketones and with different physical properties e.g. volatility and solubility), were measured above aqueous sucrose solutions [0-65% (w/v)]. As sugar concentration increased, the headspace concentration of some compounds increased, whilst others stayed the same or decreased. The changes in volatile headspace concentrations were correlated (using partial least squares regression) with a range of physicochemical descriptors which were calculated from the compound structure. The model was composed of seven physicochemical descriptors and had a regression coefficient, R2=0.74. An external test set was used to validate the model. The key descriptors in the model were (log P)2, LUMO energy and a connectivity index term. Copyright (C) 2000 Elsevier Science Ltd.
