A simple and swift preparation of 2-methyl-3-alkyl-6-ethoxyheptan-2-ols may be accomplished in two steps starting from 2-ethoxy-5-alkyl-3-,4-dihydro-2H-pyrans via chlorination of the heterocyclic compounds and subsequent reaction with MeMgBr.
2-Ethoxy-5-alkyl-3,4-dihydro-2H-pyrans react with Albui3 and through a regioselective hydride addition provide substituted cyclobutylmethanols in very good yields.
Highly porous polymers based on 2-hydroxyethyl methacrylate (HEMA) have been successfully prepared through the high internal phase oil-in-water emulsions and further functionalized. Since functionalization of alcohol containing polymers through the direct nucleophilic substitution is rather diff...
Poly(2-hydroxyethyl methacrylate) brushes were grown from a gold substrate by Atom Transfer Radical Polymerization (ATRP) and the material was applied as the gate dielectric layer in Organic Thin Film Transistor (OTFT) devices. The ATRP method provided 120 nm thick layers with relatively low rou...
Breast cancer still continues to be the leading cause of cancer-related mortality in women worldwide. Although advances have been made in the treatment of this disease during the past decade, new approaches and novel compounds are urgently needed. The aim of this study was to evaluate the cytoto...
Tris- 1, bis- 2, and mono- 3 (2-hydroxyethyl)amine-N-oxides isomers, their protonated forms, and H-complexes with acids have been studied in gas phase and DMSO solution by the quantum chemical calculations using DFT and MP2 methods. It is found that the proton affinity of the endo isomers 1a–3a...
2-(2-Hydroxyethyl)-pyridine was dehydrated to 2-vinyl-pyridine in liquid phase over solid acid catalysts, with very high selectivity and fairly good reaction rate at relatively low reaction temperature (160°C). The catalytic activity is well correlated with the presence on the catalyst surface ...
Four trans-palladium(II)- and trans-platinum(II)-chlorido complexes, trans-[PdCl2(2-hmpy)2] (1), trans-[PtCl2(2-hmpy)2] (2), trans-[PdCl2(2-hepy)2] (3) and trans-[PtCl2(2-hepy)2] (4) (2-hmpy = 2-(hydroxymethyl)pyridine and 2-hepy = 2-(2-hydroxyethyl)pyridine), have been synthesized and character...
Density (ρ) and viscosity (η) values of the binary mixtures of phenetole+1-pentanol, + 1-hexanol, + 1-heptanol, + 1-octanol, + 1-nonanol, and + 1-decanol over the entire range of mole fraction at 293.15, 298.15, 308.15, and 318.15 K have been measured at atmospheric pressure. The excess molar ...
We investigate the system consisting of phenetole (PNT) and 4-tert-butylphenol (TBP) in methanol–water (63:37 v:v) on a Zorbax 300SB-C18 column by characterising single component isotherms, by performing a large number of binary experiments of different types and by describing the experiments t...
Laser-induced fluorescence excitation and dispersed fluorescence spectra of phenetole have been measured in a cold supersonic jet expansion. The spectral features reveal the presence of only one conformer of the molecule in the environment of the jet, and the finding is consistent with the quant...
The densities and viscosities of BF3·anisole and BF3·phenetole complex were determined at T = (283.15 to 303.15)K under atmospheric pressure. The molar ratios of the complexes ranged from 0.0080 to 0.9588 for BF3·anisole and 0.0090 to 0.9850 for BF3·phenetole. The measured densities and visc...
Densities, ultrasonic speeds and refractive indices of phenetole (ethoxy benzene or ethyl phenyl ether) with N-methyl-2-pyrrolidone (NMP), N,N-dimethylformamide (DMF) and tetrahydrofuran (THF) binary mixtures over the entire mole fraction range were measured at (298, 303 and 308) K and atmospher...
Nucleophilic attack on hexafluorobenzene by sodium formanilides gave N,N′-diphenyl-2,3,5,6-tetrafluorophenylene-1,4-diamine as the main product at elevated temperature and N,N′-diformyl-N,N′-diphenyl-2,3,5,6-tetrafluorophenylene-1,4-diamine as the main compound at ambient temperature. Metalla...
Various para, meta and ortho substituted formanilides have been theoretically studied. For trans and cis-isomers of non-substituted formanilide, the calculated B3LYP vibration normal modes were analyzed. Substituent effect on the selected normal modes was described and the comparison with the av...
Challenging functionalization of C(sp3)-H has recently attracted much attention of organic chemists. In this paper, we developed a Ni(acac)2-catalyzed activation of unreactive alkanes with formanilides in the presence of carbon monoxide to furnish moderate to excellent yields of amides. This is ...
This work describes an experimental study of the electrical properties of collodion/n-ethylaniline membranes. The membranes were polarized in an electric field of 10 kV/cm at 70°C. Collodion membranes containing n-ethylaniline exhibited thermally-induced discharge currents (TDC); no TDC was obs...
The electrosynthesis of poly(N-methylaniline) (PNMA) and poly(N-ethylaniline) (PNEA) coatings on mild steel in aqueous oxalic acid solutions was carried out by potentiodynamic synthesis technique. The effects of monomer and electrolyte concentrations on electrochemical growth of PNMA and PNEA co...
Poly(N-ethylaniline) (PNEA) coatings were grown by potentiodynamic synthesis technique on 304 stainless steel (SS) alloy from 0.1 M of N-ethylaniline (NEA) in 0.3 M oxalic acid solution. Characterization of adhesive and electroactive PNEA coatings was carried out by cyclic voltammetry, FT-IR spe...
