Spontaneous reduction of samarium(III) to samarium(II) is observed upon addition of bulky cyclic triaminals to [Sm(AlMe4)3] (see scheme). The methyl groups of the organometallic precursor act as reductant, and CH activation is found as a side reaction. This reaction is the first base-induced reduction of a lanthanide(III) complex to lanthanide(II) in the complete absence of stabilizing cyclopentadienyl systems.
