The title compound, C(10)H(11)NO(5), is of inter-est with respect to its anti-dyslipidemic activity. It was prepared by reaction of 4-nitro-phenol with ethyl 2-bromo-2-methyl-propionate followed by ethyl ester hydrolysis. In the crystal, mol-ecules are linked into centrosymmetric dimers by inter-molecular O-H⋯O hydrogen bonds and the dimers are connected into chains by weak C-H⋯O inter-actions....

The title compound, C13H10N2O7S, was synthesized via a nucleophilic substitution reaction between 2,4-di-nitro-phenol and p-toluene-sulfonyl chloride. This crystal structure is a polymorph of CSD entry WUVYUH [Vembu et al. (2003). Acta Cryst, E59, o378-380]. The aromatic substituents on the sulfonate group are oriented gauche to one another with a C-O-S-C torsion angle of -62.0 (3)°. The supra-...

Conventional process of nitrating phenolic compounds involves the use excess corrosive reagents that impose environmental threats. Rapid and environmentally friendly microwave-assisted nitration phenol has been employed to limit nitric acid sulfuric acid. In this study, is reacted calcium nitrate acetic acid, which served as agents. The solution irradiated under microwave complete process. This...

The title compound, [Al(CH3)2(C30H41O)] is synthesized by the reaction of 2,6-di-adamantyl-4-tert-butyl-phenol with Al(CH3)3 in a nitro-gen atmosphere. In the mol-ecule, the coordination geometry around the Al(III) atom is slightly distorted C2O trigonal (the sum of the bond angles subtended at Al atom being 359.9°), which is rarely reported for organometallic aluminium compounds. The coordinat...

The title compound, C(12)H(8)N(2)O(5), was obtained by the reaction of 1-chloro-2,4-dinitro-benzene and phenol in the presence of potassium carbonate. The nitro-substituted benzene ring lies on a mirror plane, with one NO(2) group in the same plane and the other disordered across this plane. The phenoxy-benzene unit is placed perpendicular to this mirror, resulting in an exact orthogonal relati...

Abstract Three neutral Cu(II)/? 4 -NNNO Schiff base complexes ( 1-3 ) were prepared from the (E)-4-nitro-2-(((2-(piperazin-1-yl)ethyl)imino)methyl)phenol, tetradentate (SB) ligand, and corresponding copper(II) salts. The new SB its fully characterized by CHN-EA, standard spectroscopic, thermal, fluorescence analyses. formation of was monitored EDX, FT-IR, UV-Vis. chromotropism studies reflected...

The title mol-ecule, C(13)H(9)N(3)O(6), consists of a 2-hydr-oxy-5-nitro-phenyl-iminio group and a 4-nitro-phenolate group bonded to a methyl-ene C atom with both of the planar six-membered rings nearly in the plane of the mol-ecule [dihedral angle = 1.3 (4)°]. Each of the nitro O atoms is twisted slightly out of the plane of the mol-ecule. The amine group forms an intra-molecular hydrogen bond...

4 Nitrophenol (NP) or para nitrophenol (PNP) is one of the emerging pollutants from pesticides industries and it a major discharge any phenol consuming industry also severs as pharmaceutical wastewater. Design development photocatalytic treatment p-nitrophenol particularly to suit recovery reuse catalyst will aid in its commercial scale development. P-nitrophenol degradation has been studied ce...
