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.

Absolute rate constants and Arrhenius parameters for hydrogenabstractions (from carbon) by the t-butoxyl radical ((t) BuO.) are reported for several hydrocarbons and tertiary amines in solution. Combined with data already in the literature, an analysis of all the available data reveals that most hydrogenabstractions (from carbon) by (t) BuO. are entropy controlled (i.e., TdeltaS > deltaH, in solution
