Procedure

20.7 g of pentachlorotantalum was dispersed in 100 ml of toluene, to which 88.5 ml of isopropyl alcohol was added dropwise in a nitrogen gas atmosphere. The resultant solution was stirred at room temperature for 1.5 hours, and was then heated to 45° C. to remove the solvent therefrom by distillation. As a result, 24.8 g of dichlorotriisopropoxytantalum [TaCl2 (OCH(CH3)2)3 ] was obtained as a residue in the form of white solid.
