The adducts formed between various aryl-substituted nitrones and aryl isocyanates have been shown, using 15N n.m.r. spectroscopy and X-ray crystallography, to be substituted 1,2,4-oxadiazolidinones and not the previously reported 1,3,4-oxadiazolinones.
使用15 N nmr光谱法和X射线晶体学显示,各种芳基取代的硝酮与芳基异氰酸酯之间形成的加合物被取代的1,2,4-恶二唑烷酮,而不是先前报道的1,3,4-恶二唑啉酮。
