Abstract:
Contrary to literature reports, the o-allyloxy- and crotyloxy-acetophenone-oximes (2a, 2b) are transformed to nitrones, which undergo regio- and stereoselective intramolecular 1,3-dipolar cycloadditions, both on microwave heating under solvent free conditions and refluxing in toluene, to afford novel cycloadducts (5a, 5b); the oxazepine-N-oxide (3a) reported to be formed in 98% yield was obtained only as a minor product (~10%). However, o-cinnamyloxy-acetophenone-oxime (2c) under similar conditions undergoes intramolecular N-alkylation to afford nitrone (3c). The reactions carried out under mi

Abstract:
Three unsymmetrical bridged terphthaloyl acetophenone oxime esters have been synthesized throughout an esterification process between three acetophenone oximes and the terphthaloyl chloride under mild basic conditions. Spectroscopic techniques, such as IR, HNMR and mass spectrometer, were used to confirm the structures of the desired oxime esters. The yields of the resulting oxime esters ranged from 50% to 73%.

The objective of this study is to synthesize a number of oximes along with their terphthaloyl oxime esters derived from acetophenone, 4-methylacetophenone, 4-hydroxyacetophenone, 4-aminoacetophenone and 4-nitroacetophenone as a part of ongoing research. Five acetophenone oximes have been synthesized by refluxing the acetophenone derivative with a solution of hydroxylamine hydrochloride in the presence of potassium hydroxide. The corresponding acetophenone oximes were obtained as solid materials in moderate to good yields. The structures of the resulting oximes were confirmed using IR, NMR and

Abstract:
The report stated that the treatment of o-phenylenediamine with acetone dicarboxylic acid, acetone and acetophenone afforded 2,4,4-trimethyl-3H-5-hydro-1,5-benzodiazepine. However, direct reactions of o-phenylenediamine with oximes (acetone oxime, acetophenone oxime, and benzophenone oxime) as ketone equivalents did not occur. In the course of present investigations, it is found that dichloroamine-T can be an efficient reagent for the conversion of oximes into the corresponding carbonyl compounds.

These resulting oxime derivatives were involved in an antifungal screening against the Aspergillus niger at concentration of 30 ppm. Two commercially available antifungal agents, clorotimazole and daktarin, were employed as references at the same concentration, 30 ppm. The antifungal results for the oxime derivatives 1 – 10 showed inhibitory levels ranging from 38% to 100%, whereas the antifungal poten

A variety of ortho-, meta-, and para-substituted (-H, -F, -Cl, -CF3, -CN (meta and para only), -CH3, -OCH3, and -NO2) acetophenone oximes were synthesized and studied using laser flash photolysis (LFP) and steady-state photolysis experiments in acetonitrile with chloranil as the photosensitizer. In addition, semi-empirical (AM1) calculations were performed on the neutral species, the radical cations, and the corresponding iminoxyl radicals. The data was analyzed in terms of the electrochemical peak potentials of the oximes, the quenching rates of triplet chloranil (LFP), the calculated ionizat
