Abstract A radical α−C−H alkylation of a collection N ‐picolinamide amino acid derivatives with ethers and cycloalkanes as chemical feedstock is described. This cross‐dehydrogenative coupling distinguished by its reliable scalability removable auxiliary group, enables the assembly variety tri‐ tetrasubstituted compounds. magnified image
QSPR correlation equations were developed for the prediction of the solubilities of organic gases and vapors in water. A two-parameter correlation with the squared correlation coefficient R2 ) 0.977 gives excellent predictions for 95 alkanes, cycloalkanes, alkenes, alkylarenes, and alkynes. A satisfactory description (R2 ) 0.941) of the gas solubilities of 406 organic compounds with a large str...
A thermodynamic model is presented for the aqueous-air interface. For common organic solutes a relationship between the activity coefficients in the bulk solution and on the surface layer is deduced by using the concept of a surface monolayer. This relation has enabled development of an equation expressing the air-water surface adsorption coefficient as a function of bulk activity coefficients,...
For certain odorants, the amplitude of the rat electro-olfactogram is reduced if the olfactory epithelium is treated with the lectin concanavalin A. When normal and cycloalkanes of one to ten carbon atoms are used as odorants at equimolar concentration, the maximum reduction in amplitude is found to correlate with the size of the stimulus molecule. This observation is consistent with the notion...
