2-Phenyl-4-(3,4,5-trimethoxybenzylidene)-1,3-oxazol-5(4H)-one

Abstract

Key indicators: single-crystal X-ray study; T = 273 K; mean (C-C) = 0.003 Å; R factor = 0.043; wR factor = 0.121; data-to-parameter ratio = 12.7.The title compound, C 19 H 17 NO 5 , was synthesized as part of a continuing project involving the structures of oxazolone derivatives. The molecule adopts a Z configuration about the central olefinic bond. The 2-phenyl ring is slightly twisted out of the plane of the oxazolone ring system by 11.2 (2) . The crystal structure is stabilized by weak intermolecular C-HÁ Á ÁO hydrogen bonds. Related literature

“…All compounds have been previously prepared and characterized, − and the X-ray structure of 1i has been determined (see Experimental Section and Supporting Information, Figure S1). The structure shows the Z -configuration of the arylidene moiety and a nearly planar arrangement of the whole molecular skeleton …”

Synthesis, Characterization and Antimicrobial Screening of Some 4-Acylpyrazoloimines and Some 3d Transition Metal(II) Complexes

“…Initially researches were restricted to oxygen donor ligands [1][2][3][4][5] , however the search for pyrazolone derivatives with more sites for ligation in metal complexes has prompted other workers to synthesize imines [6][7][8][9][10][11] . The resultant compounds have several electron-rich donor centers, also they have some interesting behaviour due to their tendency to form the enol and keto form as a result of tautomeric effect 12,13 . An array of transition metal complexes with very interesting and often unusual structural and chemical properties have been reported [14][15][16][17][18][19][20] .…”

“…IR spectra were recorded on a Perkin Elmer Spectrum 100. 1 H and 13 C NMR spectra were obtained from a Bruker AV 500 MHz for 1 H and 125 MHz for 13 C using a 5 mm Quadra Nuclei Probe (QNP).…”

Synthesis, Characterization and in vitro Antibacterial Activity of Co(II), Cu(II) and Ni(II) Complexes with 4-Acylpyrazol-5-one Schiff Bases

“…The presence of various donor atoms such as O, S and N at various positions in these compounds make them to act as multidentate ligands leading to the formation of metal complexes of diverse structural types with a wide range of metals. The tendency of these molecules to form enol and keto tautomers also makes for an interesting study 7,8 . A variety of 4-acylpyrazolone metal complexes have been described in the literature [9][10][11][12][13] .…”
