Starting from the well-known stable free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH), novel diazenium betaines were obtained. These were characterized by NMR, IR, MS, ESR, CV, UV–Vis, and single crystal X-ray diffraction. A discussion about their diradicaloid character is also described.
从众所周知的稳定自由基 2,2-二苯基-1-苦基肼基 (DPPH) 开始,获得了新型二氮甜菜碱。这些通过 NMR、IR、MS、ESR、CV、UV-Vis 和单晶 X 射线衍射进行表征。还描述了关于它们的双自由基特征的讨论。
