Abstract

Mechanistic studies of one-electron reduction in water using samarium were carried out. Unexpected disproportionation in water was observed via UV−vis spectroscopic analysis. This fact indicates that low-valent samarium species can exist in water. Furthermore, the SmCl₃−Sm and SmCl₃−Mg systems were found to act as good one-electron reducing agents in water.
