Abstract
The reduction of dodecyl iodide, as model compound, with a series of lanthanoid (Ln) metals in the presence of catalytic amounts of samarium diiodide (SmI2) has been investigated in detail. The reducing activity of SmI2/Ln and the kinds of reduced products were found to be dependent on the individual Ln, but not on SmI2.

Notes
SmI2 is a useful reagent in organic synthesis, see, for example, Ref. [1].
A THF solution of SmI2 has a deep blue color with absorption maxima at 565 and 617 nm, which can be assigned to a 4f 6 → 4f 55d1 transition [32].
Most divalent species of Ln (LnI2) except SmI2 are less soluble in organic solvents, and, therefore, reduction of the oxidized surface of Ln metals with LnI2 is inefficient. In contrast, SmI2, which is soluble in THF, can efficiently reduce the oxidized surface of Ln metals. The reducing potential of SmI2 is −1.55 eV, whereas Ln metals have higher reducing potentials (−2.23 to −2.48 eV). Therefore, SmI2/Ln generally had greater reducing activity than LnI2/Ln.
When SmI2 was used without Ln, 8 % of 2 was obtained; Ref. [42].
Most of the unreacted starting material (1) was recovered. Formation of dodecyl anion was confirmed by quenching with ketone (Barbier reaction); Ref. [26].
