Experimental details
The collection method involved ω-scans of width 0.3°. Data reduction was carried out using the program SAINT+ [1] and absorption corrections were made using the program SADABS [2]. Hydrogen atoms were located from the difference Fourier map then allowed to ride on their respective parent atoms. Hydrogen atoms involved in hydrogen bonding were located from the difference map and refined freely.
Comment
Ketoximes derived from 2-aminoacetophenone and its N-substituted derivatives represent important intermediates in the synthesis of 5- and 6-membered biologically relevant heterocyclic compounds. The 2-aminoacetophenone oxime derivatives, for example, have been found to undergo methanesulfonyl chloride-mediated cyclization in the presence of triethylamine in dichloromethane at room temperature to afford the corresponding 1H-indazoles [4]. Under the same reaction conditions, the N-aryl o-aminoacetophenone oximes afforded a variety of N-aryl-1H-indazoles and the analogous benzimidazoles when 2-aminopyridine and trimethylamine were used as bases, respectively [5]. The analogous (o-amidoalkenyl)aryloximes (R = −CH = CHCH3/Ph; 1 equiv.) were previously reacted with hydroxylamine hydrochloride (1.1 equiv.) in the presence of pyridine (1.1 equiv.) in ethanol to afford the corresponding quinazoline-3-oxides and pyridinium hydrochloride by way of acid-promoted intramolecular cyclocondensation between the oxime and the amide functionality [6]. The use of an excess of hydroxylamine hydrochloride on the oxime derived from N-acetylaminoacetophenone in ethanol under reflux, on the other hand, afforded N-oxide of 2,4-dimethylquinazoline [7]. We envisioned that the ketoximes derived from the N-(2-acetylphenyl)acetamides and N-(2-acetylphenyl)benzamides would undergo the Beckmann rearrangement into the corresponding unsymmetrically substituted N,N′-diacyl-1,2-phenylenediamines. The latter have been found to undergo cyclodehydration to afford novel 2,4-dicarbo–substituted benz[d][1,3,6]oxadiazepines [8], [9], [10]. We prepared N-(2-acetyl-5-bromophenyl)benzamide as described in the literature [11]. The title crystal structure is depicted in the figure. Bond lengths and angels are all in expected ranges.
