A summary of research in the area of fluoroalkylation of electron-deficient aromatic compounds is presented. The reaction of dinitroand cyanonitroarenes with trifluoromethyl-trimethylsilane (Me3SiCF3) and tris(dimethylamino)sulfonium difluorotrimethylsilicate (TASF) and subsequently with DMD provides trifluoromethylated cyanoand nitrophenols via oxidative nucleophilic substitution of hydrogen. ...

Nitrophenols are the synthetic organic chemicals used for the preparation of synthetic intermediates, organophosphorus pesticides, and pharmaceuticals. The objective of the present study was to evaluate the effect of biofield energy treatment on the isotopic abundance ratios of PM+1/PM, and PM+2/PM in oand m-nitrophenol using the gas chromatography-mass spectrometry. The oand m-nitrophenol were...

Decasubstituted pillar[5]arenes containing amidopyridine fragments have been synthesized for the first time. As was shown by UV-vis spectroscopy, with p-amidopyridine form supramolecular associates Cu(II) and Pd(II) cations in methanol a 2:1 ratio. Using sol-gel approach these are transformed into metallo-supramolecular coordination polymers (supramolecular gels) which were characterized as amo...
