摘　　要：报道以取代芳胺为原料经重氮化,叠氮化,1,3-偶极环加成反应得到1-取代芳基-4-乙氧羰基-5-胺基-1,2,3-三唑,并以此为原料合成了一些新的Aza-Wittig试剂——1-取代芳基-4-乙氧羰基-5-三苯膦化亚胺基-1,2,3-三唑。Some new Aza - Wittig reagents ( 1 - substituted aryl - 4 - ethoxycarbonyl - 5 - [ (triphenylphos-phoranylidene)amino] - 1, 2, 3 - triazoles) were prepared from 1 - substituted aryl - 4 - ethoxycarbonyl - 5 - amino, triphenylphosphine, and hexachloroethane in the presence of triethylamine. The products were characterized by IR, 1H NMR, and MS spectroscopy and elemental analysis.
