Naphthalene → Naphthalene sodium

Participants

Reaction Steps

1 g freshly pickled sodium and 1.28 g of pure naphthalene (Aldrich) are introduced into a dry balloon-flask of a capacity of 250 ml, under a dry nitrogen stream. 100 ml of tetrahydrofuran dried by reflux on a benzophenone-sodium complex and distilled just prior its use are then added under an atmosphere of dry nitrogen. After stirring during 4 hours at room temperature, the naphthalene-sodium complex is formed; the concentration of this complex is of 0.1 mol/liter.
