source: Chiba UniversitySamarium (Sm), a rare earth metal, is important to organic chemists because of the ability of its divalent compounds to efficiently perform single-electron transfer reductions.Samarium iodide (SmI2) is moderately stable and can operate under mild conditions at room temperature, making it highly useful for producing pharmaceuticals and biologically active materials. However, most reactions require SmI2 in quantities equal to or greater than the stoichiometric amount and necessitate the use of harmful chemicals, making the process resource-intensive and expensive to manag...
