To a stirred solution of methyl 2-chloro-3-oxobutanoate (1.64 g, 10 mmol) in ethanol (100 ml) was added sodium acetate trihydrate (1.30 g, 10 mmol). The mixture was chilled to 273 K and then treated with a cold solution of p-nitrobenzenediazonium chloride, prepared by diazotizing p-nitroaniline (1.38 g, 10 mmol) dissolved in 6M hydrochloric acid (6 ml) with a solution of sodium nitrite (0.70 g, 10 mmol) in water (10 ml). The addition of the diazonium salt solution was carried out with rapid stirring over a period of 20 min. The reaction mixture was stirred for further 15 min. and left for 3 h in refrigerator. The resulting solid was collected by filtration and washed thoroughly with water. The crude product was crystallized from ethanol to give the corresponding hydrazonoyl chloride.
Carbon-bound H-atoms were placed in calculated positions [C—H 0.95 to 0.98 Å, Uiso(H) 1.2 to 1.5Ueq(C)] and were included in the
in the riding model approximation.The amino H-atom was located in a difference Fourier map, and was freely refined.
The final difference Fourier map had a peak in the vicinity of H6.

We have previously reported the synthesis of ethyl (Z)-2-chloro-2-(2-phenylhydrazin-1-ylidene) acetate by the reaction of benzenediazonium chloride with ethyl 2-chloro-3-oxobutanoate (Asiri et al., 2010). The compound is an ester. In the present study, the use of a substituted benzenediazonium chloride and the methyl ester (instead of the ethyl ester) afforded a 1-chloro-1-(arylhydrazono)-2-propanone. Such ketones are intermediates in the synthesis of pyrazoles (Sayed et al., 2002) and other heterocycles (Benincori et al., 1990). In the 4-nitro substituted compound (Scheme I, Fig. 1), the non-hydrogen atoms lie on a plane [r.m.s. deviation 0.111 Å] (Scheme I, Fig. 1). The Caryl–N(H)–N═ C(S)═O portion adopts an extended zigzag conformation. Adjacent molecules are linked by an N–H···Ocarbonyl hydrogen bond to form a chain running [1 0 1].
