A newapproach to the synthesis of polyfunctional pyrazolyl-substituted nitronylnitroxides was developed based on the presynthesized pyrazole derivatives prepared by 1,3-dipolar cycloaddition. The structures of the resulting mono-and biradicals were confirmed by X-ray diffraction.
基于通过 1,3-偶极环加成制备的预合成吡唑衍生物,开发了一种合成多功能吡唑基取代的硝酰基氮氧化物的新方法。通过 X 射线衍射证实了所得单自由基和双自由基的结构。
