Synthesis of 2-hydroxy(methoxy)-4,4′-biphenyldicarboxylic acids was developed. Based on their reactions with o-aminophenols we prepared for the first time 4,4′-bis[5-alkyl(aryl)benzoxazol-2-yl]-2-hydroxy-(alkoxy)biphenyls, which might be of interest as luminescent dyes. Hydroxy compounds in a salt form possess abnormally high Stokes shift. 相似文献

The conditions for the acylation of (–)-menthol with monochloroacetyl chloride have been studied. Amino esters of (–)-menthol have been obtained by the nucleophilic replacement of the chlorine in (–)-menthol monochloroacetate by residues of secondary amines. Their properties and their mass, IR, and13C NMR spectra are described.Institute of Physical Organic Chemistry, Academy of Sciences of the Belorussian SSR, Minsk.

A series of novel double quaternary ammonium salts based on 5,5-dioxo-5H-dibenzo[b,d]thiophene has been prepared via quaternization of the corresponding 3,7-bis(chloromethyl)dibenzothiophene-5,5-diones with various N,N-dimethylalkylamines. Pronounced fungicidal activity of the C1-substituted quaternary ammonium salts has been observed. 相似文献

An attempt was made to prepare 4,4'-bis[5-alkyl(aryl)benzoxazol-2-yl]biphenyls by reaction of dimethyl 4,4'-biphenyldicarboxylate with substituted o-aminophenols in a high-boiling solvent in the presence of boric acid. 相似文献

Preparation method was developed and a series of new linear polyconjugated compounds was obtained with (1,3-benzoxazol-2-yl)ethenyl,
(5-oxo-2-phenyl-1,3-oxazolidine)methyl moieties in the positions 3, 7 of dibenzothiophene-5,5-dione frame and with peripheral alkoxy- and alkylamine substituents in the position 1. Compounds obtained possess a strong luminescence in solutions, in the solid state, and exhibit electroluminescent properties. 相似文献
