EPR Studies on the SmI2-Promoted Coupling of N-(N‘,N‘-Dialkylaminoalkyl)benzotriazoles
摘要:
[GRAPHICS]Radicals generated in the Sml(2)-promoted coupling of N-(N',N'-dialkylaminoalkyl)benzotriazoles 1 have been detected using the EPR spin-trapping technique, Single electron transfer (SET) between 1 and Sml(2) is discussed as a mechanism for the formation of the radicals.

N-(N′,N′-Dialkylaminoalkyl)benzotriazoles, derivedfrom 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.
