Azidopyridazines 3, 4, 24 and tetrazolo[1,5-b]pyridazines 10, 13, 28 can be converted to the corresponding aminopyridazines, by reaction with triphenylphosphine via phosphazenes and subsequent hydrolysis (Staudinger reaction).
叠氮吡哒嗪3、4、24和四唑并[1,5-b]吡哒嗪10、13、28可通过与三苯基膦反应生成膦嗪并随后进行水解(Staudinger反应),转化为相应的氨基吡哒嗪。
