Abstrakt:	The reaction of P-(morpholin-1-yl)propioamidoxime with aromatic sulfonyl chlorides (p-XC6H4SO2Cl; X = CH3O, CH3, H, Br, Cl, NO2) in chloroform in the presence of triethyl-amine does not produce expected O-arylsulfonyl-β-(morpholin-1-yl)propioamidoximes; instead, this reaction affords isomers of the latter compounds, 2-amino-8-oxa-l,5-diazaspiro[4.5]dec-1-ene-5-ammonium arylsulfonates. The structures of the reaction products were established by physicochemical methods, spectroscopy, and X-ray diffraction. [ABSTRACT FROM AUTHOR]
