    MECHANOCHEMICAL SYNTHESIS OF POLYMERIC SHIFF BASES VIA THE POLYCONDENSATION REACTIONS BETWEEN DIAMINES AND DIALDEHYDES

    Full text link
    During last two decades the mechnochemical synthesis became good alternative to the traditional organic synthesis. For the polymer chemistry mechanochemical polymerization is constituted as sustainable alternative to the solution polymerization.This work was supported by Russian Foundation for Basic Research (# 19-53-55002)

    A rational protocol for the synthesis of 1-(2-pyridyl)isoquinolines

    Full text link
    Aza-Diels-Alder reaction between 3-(2-pyridyl)-1,2,4-triazines and 1-morpholinocyclohexene followed by aromatization of the cyclohexene moiety affords 1-(2-pyridyl)isoquinolines. Crystal structures of two tetrahydroisoquinolines were confirmed by X-ray diffraction analysis. © 2013 Mendeleev Communications. All rights reserved

    Synthesis of meso-2,2’-bipyridyl-substituted calix[4]arenes and their response to metal cations

    A convenient synthetic approach to meso-substituted with 2,2’-bipyridine and 1-(pyridin-2-yl)isoquinoline residues calix[4]arenes is reported. This approach involves the reaction of generated in situ 2-lithio-calix[4]arene with 1,2,4-triazine precursor with the following aromatization of the obtained adduct, and the aza-Diels-Alder reaction of the 1,2,4-triazinyl-substituted calix[4]arene with 2,5-norbornadien or in-situ generated 1,2-dehydrobenzene. The UV/fluorescence response of thus obtained meso-pyridyl-substituted calix[4]arenes to metal cations is studied

    Detection of Anti-viral Drug Riamilovir and Herbicides in Aqueous Media by Using Pyrene-based Fluorescent Chemosensors

    Two ethyleneglycol esters of 1-pyrene carboxylic acid were studied as chemosensors for the fluorescence “turn-off” detection of two nitro-containing analytes, such as antiviral drug Riamilovir (Triazavirin ®) and herbicidal agent dinitro-ortho-cresol (DNOC). In both cases the dramatic fluorescence quenching was observed with quenching constants as high as 3·104 M-1 and limits of detection (LOD) as low as 100 ppb
