Sm(II)-Mediated Reduction in Water: Importance of the Additive in the Proportionation of SmCl₃ and Sm

Abstract

Mechanistic studies of the SmCl₃-Sm system in water were carried out. The addition of N,N-dimethylacetoamide (DMA) enhanced the reactivity of the one-electron reduction. According to the ultraviolet–visible (UV-vis) analysis, DMA was found to accelerate proportionation of SmCl₃ and Sm.
