Condensation of benzotriazole, an aldehyde, and either an amine or amide using the method of Katritzky gave N-[1-benzotriazol-1-yl)alkyl]amides and -amines, which were treated with tributylstannyllithium or trimethylstannyllithium to afford N-[1-(trialkylstannyl)alkyl]amides and -amines, respectively. These compounds are important precursors of nitrogen-substituted organolithium reagents.
用 Katritzky 的方法将苯并三唑、醛和胺或酰胺缩合,得到 N-[1-苯并三唑-1-基)烷基]酰胺和-胺,再用
三丁基锡锂或
三甲基锡锂处理,分别得到 N-[1-(三烷基
锡)烷基]酰胺和-胺。这些化合物是氮代
有机锂试剂的重要前体。
