Abstract:	Reactions of alicyclic 2-hydroxyamino oximes with pentafluorophenylglyoxal afford mixtures of annelated derivatives of 2-pentafluorophenylpyrazine 1,4-dioxide and tetrafluoro- 10H-imidazo1,2-b]1,2]benzooxazin-10-one. The structures of the latter were established by X-ray diffraction analysis.Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 8, pp. 1636–1639, August, 2004.

Keywords:	tetrafluoro-10H-imidazo[1 2-b][1 2]benzooxazin-10-one 2-hydroxyamino oximes pentafluorophenylpyrazine 1 4-dioxides X-ray diffraction analysis
