TLDR
In this article, the authors used ultrasound (20 kHz) to synthesize samarium(II) diiodide and triflate reductants in a wide range of solvents including alcohols.Abstract:
Ultrasound (20 kHz) was used to prepare samarium(II) diiodide (SmI2), samarium(II) dibromide (SmBr2), and samarium(II) triflate (SmOTf)2. The method described herein provides a straightforward and rapid approach to the synthesis of SmII compounds not accessible by other means. Of particular importance is the fact that this approach can be used to produce SmII-based reductants in a wide range of solvents including alcohols. (© Wiley-VCH Verlag GmbH & Co.

Recent advances in the chemoselective reduction of functional groups mediated by samarium(II) iodide: a single electron transfer approach.
TL;DR: Samarium(II) iodide reductants have emerged as powerful single electron donors for the highly chemoselective reduction of common functional groups, which opens up new prospects for unprecedented transformations via radical intermediates under mild regio-, chemo- and diastereoselectives conditions that are fully orthogonal to hydrogenation or metal-hydride mediated processes.

Preparation of Samarium(II) Iodide: Quantitative Evaluation of the Effect of Water, Oxygen, and Peroxide Content, Preparative Methods, and the Activation of Samarium Metal
TL;DR: The studies confirm that SmI(2) is a user-friendly reagent and suggest that the quality of samarium metal is an important factor and that the use of low quality metal is the main cause of failed preparations of the reagent.

SmI2(H2O)n Reduction of Electron Rich Enamines by Proton-Coupled Electron Transfer
Scott S. Kolmar,James M. Mayer +1 more
TL;DR: The reduction of several enamines by SmI2(H2O)n shows that this reagent is a very strong hydrogen atom donor as well as an outer-sphere reductant.
