N-Substituted aminomethylphenol (Mannich base) and 3,4-dihydro-2H-3-substituted 1,3-benzoxazine (benzoxazine) were synthesized from substituted phenol (p-cresol, phenol, p-chlorophenol), substituted aniline (p-toluidine, aniline, p-chloroaniline) and formaldehyde to study influence of substituent on equilibrium of benzoxazine synthesis from Mannich base and formaldehyde. (1)H-NMR and charges of...

The article provides a comparative analysis of data on the content macro- and micronutrients, as well determination identification biologically active substances in bioextracts obtained with distilled water (BE-I) 70% ethanol (BE-II) from shell common hazelnut (Corylus avellana L.) plant widespread northwestern region Azerbaijan. It was established that BE-I BE-II have same mineral composition ...

The title compound, 2C(21)H(19)N(3)O(2)·H(2)O, was synthesized by a Schiff base condensation of 2,6-diformyl-pyridine with 2-amino-4-methyl-phenol in ethanol. In the crystal, two mol-ecules of 2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine dimer-ize via hydrogen bonding to a water mol-ecule, which lies on a twofold axis. There are also intra-molecular phenol-imine hydrogen bonds. ...

The mol-ecule of the title compound, C(15)H(14)N(2)O(2) is almost planar, the dihedral angle between the 6-methyl-1H-benz-imidazole plane and the 2-methoxy-phenol plane being 6.9 (2)°. An intra-molecular O-H⋯N hydrogen bond is present. Adjacent mol-ecules are linked by N-H⋯O hydrogen bonds into a three-dimensional network structure. The benzoimidazole methyl group and its attached C atom are po...

A novel Schiff base (Z)-4-(((2-hydroxy phenyl)amino)(phenyl)methylene)-3-methyl-1-phenyl-1Hpyrazol-5(4H)-one and its analogues were synthesized by condensation of 5-methyl-2-phenyl-4-substituted pyrazolin3-one with 2-amino phenol from alcoholic solution.Schiff base ligands arecharacterizedby IR, UV, NMR, elemental analysis and single crystal Xray diffraction analysis. These potential ligands ar...

The present investigation deals with synthesis of new acid dyes from 4-amino-1-(4-sulfophenyl)-3-methyl-5-pyrazolone and phenol derivatives and their metal complexes (Cu (II) and Fe (II)). The phenol derivatives include 4-chlorophenol, 4-nitrophenol, 4-hydroxybenzene sulfonic acid, 2-nitrophenol-4-sulfonic acid, resorcinol and bisphenol A and bisphenol S. The newly synthesized dyes were applied...
