8-naphthyridine from the corresponding dialdehydes and N,N′-dihydroxy-2,3-diamino-2,3-dimethylbutane in the presence of catalytic amounts of SeO2. Mild oxidation afforded the corresponding stable imino-nitroxide biradicals 4 to 11.
由吡啶,2,2'-联吡啶,1,10-菲咯啉,哒嗪和1,8-萘啶基于相应的二醛和N,N'-二羟基-2,3-二氨基-选择性合成双-N-羟基咪唑烷2,3-二甲基丁烷在催化量的SeO 2的存在下。轻度氧化得到相应的稳定的亚氨基硝基氧双自由基4至11。
