Sodium naphthalene is an organic salt with the chemical formula Na + [C 10 H 8] −. In the research laboratory, it is used as a reductant in the synthesis of organic, organometallic, and inorganic chemistry. It is usually generated in situ. When isolated, it invariably crystallizes as a solvate with ligands bound to Na +. [1]
With alkali metals, naphthalene forms the dark blue-green radical anion salts such as sodium naphthalene, Na + C 10 H − 8. The naphthalene anions are strong reducing agents. Naphthalene can be hydrogenated under high pressure in the presence of metal catalysts to give 1,2,3,4-tetrahydronaphthalene(C 10 H 12), also known as tetralin.

Sodium naphthalene, a salt containing the radical anion of naphthalene as the anion. In organic chemistry, a radical anion is a free radical species [1] that carries a negative charge. Radical anions are encountered in organic chemistry as reduced derivatives of polycyclic aromatic compounds, e.g. sodium naphthenide.
The enamine eliminates sodium bisulfite with formation of naphthylamine 6. It is important to stress that this is a reversible reaction. The reaction is summarized as follows: The Bucherer carbazole synthesis is a related reaction.

With alkali metals, 1-methylnaphthalene forms radical anion salts such as sodium 1-methylnaphthalene. Compared to its structural analog sodium naphthalene , sodium 1-methylnaphthalene is more soluble, which is useful for low-temperature reductions.
Virtually all sodium etching bond strengths reported in academic journals predate the advent of glymes as carriers for sodium naphthalene complex. In adhesion tests per ASTM D4541, in which an aluminum stud is bonded to the test surface and the stud is pulled in the direction normal to the surface, both surfaces of the failure interface were ...
