Copper(II) triflate or Et3N have been found to catalyze, under ambient conditions, the addition of a cyanide anion, such as trimethylsilyl cyanide or acetone cyanohydrin, onto in situ generated imines, furnishing α-aminonitriles in excellent yields.

(abbreviated as 4‐OHBAY or XBAOH‐4′) were synthesized, and their ERed values were measured. Then, 127 compounds were taken as a complicated ERed data set, which involved 28 compounds (4‐OHBAY and XBAOH‐4′) of this work and 99 compounds XBAY reported by Luo. Based on these data ERed set, through a quantitative regression analysis method and comparison of the factors affecting the ERed, the following results

permittivities of solvents and KT of p-hydroxybenzylideneaniline in the corresponding solvent with regression coefficient of 0.998 supported specific interactions between the solvent and the aldimines. But the occurrence of a scattering distribution of the relative permittivities of solvents with the KT's of o-hydroxybenzylideneaniline revealed no specific interaction of these molecules with the solvents. The oscillator

日期:——
Solid-phase synthesis combined with infrared irradiation promoted the formation of a series of Schiff bases in the condensation reaction between substituted benzaldehydes and anilines, in the solvent free. Benzaldehydes and anilines, containing either electron withdrawing or electron-releasing groups, were evaluated their substituent effect on the formation of the Schiff bases. Moreover, this new procedure is environmentally benign because no solvent was employed in the transformations.

Effect of substituents on the ultraviolet (UV) spectra of supermolecular system involving silver nanoparticles (AgNPs) and Schiffbases was investigated. AgNPs and 49 samples of model compounds (MC), bi‐aryl Schiffbases containing hydroxyl (XBAY, involving 4‐OHArCHNArY, 2‐OHArCHNArY, XArCHNAr‐4′‐OH, and XArCHNAr‐2′‐OH), were synthesized. The size of AgNPs was characterized by transmission electron
