文摘

The uranium(III) and uranium(IV) iodide complexes UI₃(1,4-dioxane)_1.5 and UI₄(1,4-dioxane)₂ have been easily prepared in high yield by reacting uranium turnings with a 1,4-dioxane solution of iodine under mild conditions. The two complexes exhibit outstanding thermal stability and are excellent precursors to a variety of uranium(III), uranium(IV), and uranium(VI) alkoxide, amide, organometallic, and halide compounds, including a safe, room-temperature synthesis of [UCl₄(1,4-dioxane)]₂, which is a useful synthetic alternative to UCl₄.
