Synthesis of Vicinal Diamines by SmI2-Promoted Reduction of N-(N',N'-Dialkylaminoalkyl)benzotriazoles

Aurrecoechea, Jose M.,Fernandez-Acebes, Alvaro

, p. 4763 - 4766 (1992)

N-(N',N'-Dialkylaminoalkyl)benzotriazoles, derived from aldehydes and secondary amines, react with one equivalent of samarium iodide (SmI2), under mild conditions, to afford tertiary vicinal diamines, as a result of C-C coupling between two dialkylaminoalkyl moieties.
