| Abstract: | 3(Z)-Benzoylmethylidene-6-nitro-3,4-dihydro-2H-1,4-benzooxazin-2-one reacts with (COCl)2 as imino enol rather than enamino ketone. The reaction is accompanied by replacement of the hydroxy group by chlorine. The molecular and crystal structures of the starting 1,4-benzooxazin-2-one and its chlorinated derivative were studied by X-ray diffraction analysis. |
