Sodium sticks, in mineral oil is used for reviews of Na metal - ammonia (Birch) reductions, for preparation of sodamide in liquid ammonia and for use in an acyloin synthesis promoted by sonication.
The classical Wurtz coupling reaction of alkyl halides is, in its intramolecular form, a useful method for closing small rings: Org. Synth. Coll., 6, 133 (1988); review: Russ. Chem. Rev., 51, 368 (1982).
