有机铝试剂在一些简单化学反应中具有日益增加的重要作用。较之以往所发表的一些标准方法,R_2Alx(X=NR_2、SR)型试剂,通常具有适应范围广、反应条件温和的优点。本文作者介绍双功能团化合物诸如1,2-二氨基乙烷、1,2-二氨基苯及2-巯基苯胺与三甲基铝结合所生成的试剂,能够与各型羧酸酯类反应,分别合成2-咪唑啉、苯骈咪唑 Organoaluminum reagents have an increasingly important role in some simple chemical reactions. Compared with some standard methods published in the past, R_2Alx (X = NR_2, SR) type reagents usually have the advantages of wide adaptability and mild reaction conditions. The authors describe the reagents generated by the combination of bifunctional compounds such as 1,2-diaminoethane, 1,2-diaminobenzene and 2-mercaptoaniline with trimethylaluminum to react with various carboxylic acid esters, Respectively synthesized 2-imidazoline, benzimidazole
