Synthesis ofN-[1-(Trialkylstannyl)alkyl]amides and -amines by the Displacement of Benzotriazoles with Trialkylstannyllithiums

All articles of this category 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.
