(4-Chlorobenzoyl)(4-chlorophenyl)amino 3-(2-nitrophenyl)propanoate
In the title hydroxamic acid derivate, C22H16Cl2N2O5, the nitro-substituted benzene ring forms dihedral angles of 14.11 (15) and 16.08 (15)°, with the 4-chloro-benzoyl and 4-chloro-phenyl benzene rings, respectively. The dihedral angle between the chloro-substituted benzene rings is 2.28 (13)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming chains along [100].
متن کاملCrystal Structure of Schiff base Compound 2-[(2-chloro-4-nitrophenyl) iminomethyl] phenol
Single crystals of Schiff base compound 2-[(2-chloro-4-nitrophenyl) iminomethyl] phenol (1) were grown by the slow evaporation technique at room temperature. The crystal structure of the title compound was determined by single crystal X-ray diffraction. The title compound crystallizes in the monoclinic system, space group P21, with two symmetry independent molecules. Intramolecular O-H···N hydr...
متن کاملCHEMICAL SYNTHESIS OF p-NITROPHENYL p-NITROPHENYL ~LAh%INARABIOSlDE*
Condensation OF tetra-U-acetyk-D-glucopyranosyl bromide withpnitrophenyl 4,6-O-benzylidene-/?-D-glucopyranoside followed by appropriate deblocking reactions gives rise to an approximately equimolar mixture of p-nitrophenyl @,ophoroside and pnitrophenyi Plaminarabioside. The two glycosides are readiIy separated and isolated in pure form by cellulose-column chromatography.
متن کاملPotassium p-nitrophenyl sulfate.
The crystal structure of the title compound, K+.C6H4NO6S-, is built up from p-nitrophenyl sulfate anions and potassium cations. Adjacent anions form dimers, which are linked together in a three-dimensional network via short C-H...O contacts. The coordination sphere of the K+ ions may be described as a distorted square antiprism. The crystal structure is further stabilized by pi-pi stacking inte...
متن کاملIntramolecular electron transfer reactions in meso-(4-nitrophenyl)-substituted subporphyrins.
A2B-type meso-(4-nitrophenyl)-substituted subporphyrins have been synthesized and shown to undergo very fast photoinduced intramolecular charge separation (CS) and charge recombination (CR) between the subporphyrin core and the meso-4-nitrophenyl group in CH2Cl2 as probed by femtosecond time-resolved transient absorption spectroscopy. Red-shifted emissions were detected from charge-separated st...
