The Crystallographic, Spectroscopic and Theoretical Studies on (E)-2-[((4-fluorophenyl)imino)methyl]-4-nitrophenol and (E)-2-[((3-fluorophenyl)imino)methyl]-4-nitrophenol Compounds
In this study, two new salicylideneaniline derivative compounds which are an isomer of each other have been synthesized and characterized by X-Ray Diffraction (XRD) technique, IR spectroscopy, and theoretical method. While (E)-4-(dihydroxyamino)-2-(((4-fluorophenyl)imino) methyl)phenol (1), crystalizes triclinic P-1 space group, (E)-4-(dihydroxyamino)-2-(((3-fluorophenyl)im...
متن کاملCrystal structure of 2-(4-tert-butylphenyl)-3-hydroxy-4H-chromen-4-one
Yellow-green fluorescent crystals of the title compound, C19H18O3, were obtained by the reaction of hy-droxy-aceto-phenone and 4-tert-butyl-benzaldehyde with hydrogen peroxide as oxidant. The plane of the benzene ring is slightly twisted to the mean plane of the 4H-chromene-4-one moiety (r.m.s. deviation = 0.0191 Å) by 10.53 (8)°. In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen...
متن کاملSynthesis and Crystal Structure of 1-(3-Fluorophenyl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one
The base catalyzed intramolecular nucleophilic cyclization of 1-(2-bromobenzoyl)-3-(2-fluorophenyl)thiourea (1) in the presence of N,N-dimethyl formamide (DMF) afforded the 1-(3-fluorophenyl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one (2) by an intramolecular nucleophilic substitution SNAr mechanism. The structure was supported by the spectroscopic data and unambiguously confirmed by the single c...
متن کاملCrystal structures of 4-methoxy-6-methyl- and 4-hydroxy-6-methyl-2-pyrones.
interesting results because of the regular arrangement of the molecules in the environment.1–3 We previously reported on the photocycloaddition reaction of 4-methoxy-6-methyl-2-pyrone (1a) (Fig. 1) with maleimide (2) in the solid state to give a highly stereoselective [2 + 2] cycloadduct4 owing to the formation of two sets of 1:1 complex crystals between (1a) and (2) (Fig. 1).5 The crystal show...
متن کاملCrystal structure of cis-1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one
In the title compound, C16H22N2O, the azepan-2-one ring adopts a chair conformation, while the 1,2,3,4-tetra-hydro-pyridine ring adopts a half-chair conformation. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming supra-molecular chains propagated along [10-1], with weak C-H⋯O inter-actions occurring between the chains.
