How is Samarium(3+) tri(2-propanolate) (CAS: 3504-40-3) typically synthesized?

Samarium(3+) tri(2-propanolate) is typically synthesized by reacting samarium(III) chloride with 2-propanol in an anhydrous and inert atmosphere. The reaction involves a complexation process where the 2-propanol ligands replace the chloride ions. This method ensures high purity and selectivity. The product is usually obtained as a white precipitate, which can be filtered and dried under vacuum.
