Lithium naphthalenide reduction mechanism
Lithium naphthalene is an organic salt with the chemical formula Li C 10H 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. Lithium naphthalene crystallizes with ligands bound to Li . Web20 okt. 2015 · FTIR investigations support a two-step mechanism for Li x N (THF) n formation. For 0 < x < 1 the solutions consist of mixture of lithium-free naphthalene Li 0 N (THF) n and lithium-bound naphthalene Li 1 N (THF) n whereas for 1 < x < 2 the solutions consist of mixture of Li 1 N (THF) and Li 2 N (THF) n solutes.
