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-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- [(triphenylphosphoranylidene)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.

Key words: PYRRODIAZOLE P, TRIPHENYLPHOSPHINE P, STRUCTURE CHARACTERISTICS
