在多聚磷酸三甲基硅酯(PPSE)的存在下,2,6-二异丙基苯胺和丁二酸缩合可以高产率地得到N,N′,N″-三(2,6-二异丙基苯胺基)-2,5-二亚胺吡咯(1).化合物1经过了元素分析、红外光谱、氢谱、高分辨质谱和单晶结构衍射的表征.
N,N′,N″-tris(2,6-diisopropylphenyl)-2,5-diiminopyrrolidine (1) is produced in high yield from the reaction of succinic acid and 2,6-diisopropylaniline in the presence of polyphosphoric acid trimethylsilyl ester (PPSE). Compound 1 is characterized by elemental analysis, FT-IR spectrum, 1H NMR, HRMS, and X-ray single crystal structure diffraction.
