N2 - Samarocene oxide [Cp∗2Sm-O-SmCp∗2] is mostly considered as an undesired decomposition product of the well-established but highly air-sensitive samarocene, [Cp∗2Sm(thf)2]. [Cp∗2Sm-O-SmCp∗2] is often formed by accidental exposure of [Cp∗2Sm(thf)2] to air or wet solvents. We show here that [Cp∗2Sm-O-SmCp∗2] acts as a mild oxide base and thus is a valuable synthetic equivalent for "O2-". The reaction of [Cp∗2Sm-O-SmCp∗2] with the inorganic and organic anhydrides COS, CS2, SO2, SO3, Re2O7, and (PhC(O))2O at room temperature resulted in each case in an O2- insertion. The corresponding products were isolated as their samarium complexes.
