新型胍类化合物的催化合成

摘要

Diamido supported rare earth metal amides with general formula {(CH2 SiMe2 )[(2 ,6-i Pr2 C6 H3 )N]2}SmN (SiMe3 )2 (TH F) was used as highly efficient catalyst for the guanylation of sec-ondary amines ,aromatic amines and heterocyclic amines under mild reaction conditions and low catalyst loading .The products were characterized by IR ,1 H NMR ,13C NMR .%将稀土双胺化合物｛（CH2 SiMe2）[（2，6-iPr2C6 H3）N]2｝SmN（SiMe3）2（THF）应用于胍类化合物的催化合成，在较低催化剂载入量（3％ mol）和温和的反应条件（室温，6小时）下实现对脂肪仲胺、芳香胺、杂环胺等的胍化，得到一系列新型胍类化合物，化合物的结构经红外、核磁氢谱和碳谱表征。
