几种新的氮杂-Wittig试剂1-取代芳基-4-乙氧羰基-5-三苯膦化亚胺基-1,2,3-三唑的合成与表征

Some New Aza-Wittig Regents Synthesis and Characterization of 1-Substituted Aryl-4-ethoxycarbonyl-5- [(triphenylphosphoranylidene)amino]-1,2,3-triazoles

以 1 -取代芳基 -4 -乙氧羰基 -5 -胺基 -1 ,2 ,3 -三唑为原料合成了 5种新的氮杂 -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。其结构经元素分析、IR,1H NMR和 MS确定。

Five new Aza-Wittig regents ——1-substituted aryl-4-ethoxycarbonyl-5-[(triphenylphos-phoranylidene)amino]-1,2,3-triazoles were preparad from 1-substituted aryl-4-ethoxycarbonyl-5-amino and triphenylphosphine in the presence of triethylamine and hexachloroethane. The products were characterized by elemntal analysis, IR,1H NMR and MS.
