    • 4. To the distillate several pieces of sodium (or potassium) and benzophenone was added, the mixture was sonicated until it became permanent deep blue and THF was distilled using a Vigreux column. The contact with ambient atmosphere should be avoided.

    • From lithium (immersed in benzene), a piece (0.15-0.20 g) was taken, dried with filter paper and hammered to a thin foil on a greased with paraffin oil anvil. The foil was folded several times, and hammered again. The operation was repeated several times and finally the wound foil was cut with scisors in such a way that the pieces of lithium fell directly into the flask.
