Separation of racemic salycylaldehydes containing isobornyl substituent using (R)-1-phenylethylamine
摘要:
Racemic salicylaldehydes containing isobornyl substituent were separated by their conversion into diastereomers by the reaction with (R)-1-phenylethylamine. The absolute configuration of the intermediate Schiff bases and separated aldehyde eneatiomers was established by XRD analysis.
Alkylation of phenol with camphene in the presence of heteropolyacids supported on metal oxides
摘要:
Alkylation of phenol with camphene in the presence of supported heteropolyacids is studied. The main reaction products are found to be phenyl isobornyl ether, 2-isobornylphenol and 2-isocamphylphenol, the ratio between them being determined by the nature of heteropolyacid and carrier (ZrO2 or TiO2).

A structure — hemolytic activityrelationship in isobornylphenol derivatives was analysed. The morphological transformation of erythrocytes under the influence of some representatives of this class of compounds was demonstrated by scanning electron microscopy. The hemolytic activity of the test compounds can vary within wide limits, depending on the structure and position of substituents determining

The alkylation of phenol by β-pinene using Al(OPh)3 as a catalyst was studied. It was found that the composition of the products depended on the ratio of starting materials. The principal products were chromane-type ethers with an equimolar ratio of starting materials and an excess of phenol. ortho-Alkylated phenol and an ether with a terpene substituent of bornyl structure were formed with a two-fold

Provided is a transparent conductive ink which contains metal nanowires and/or metal nanotubes as a conductive component and can form a coating film which has good conductivity and a high light transmittance property, and also provided is a transparent conductive pattern forming method wherein this transparent conductive ink is used for forming a transparent conductive pattern by simple production steps, to thereby suppress the production cost and environmental load. At least one of metal nanowires and metal nanotubes are dispersed in a dispersion medium containing a shape-holding material which contains an organic compound having a molecular weight in the range of 150 to 500 and which has a viscosity of 1.0×103 to 2.0×106 mPa·s at 25°C, to prepare a transparent conductive ink. A transparent conductive pattern is formed by printing a pattern having an arbitrary shape on a substrate using this transparent conductive ink, subjecting the pattern to a heating treatment to dry the pattern, and subjecting the pattern which has been dried to pulsed light irradiation.
