Thulium(III) iodide anhydrous TmI3 CAS 13813-43-9 For Thulium(III) Salts Additive

Anhydrous thulium iodide is a chemical with the formula TmI₃ and a molecular weight of 549.6476, which is a bright yellow hexagonal crystal. It is stable at room temperature and pressure, but it needs to avoid the influence of moisture, moisture and light. Anhydrous thulium iodide can be prepared by the reaction of metal thulium with mercury iodide in a closed tube.

The ability of anhydrous thulium iodide to gradually change back to yellowish trivalent thulium ions under certain conditions makes it a potential reducing agent of choice in organic chemistry. In addition, anhydrous thulium iodide can promote the cross-coupling reaction of 2-acetylthiophene or 2-thiophene carboxylate with aldehydes and ketones in THF at room temperature. It has potential applications in key areas such as renewable energy, magnetic technology and nuclear waste disposal.
