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]
For example, this is why the template writes "(at 0 °C)". For this, you may want to experiment with parameter input too - or propose improvements. All this can vary across the values (data rows). So depending on the row and the specific value, additional formattings may be added by the template (e.g., a newline <br/>) Central data values
The fluorine-to-carbon atomic ratio (F/C ratio) is reduced from PTFE's theoretical ratio of 2.0 to 0.2 or less, after exposure to sodium naphthalene for 1 minute. [ 6 ] [ 7 ] [ 8 ] The fluorine atoms are replaced with hydroxyl, carbonyl, and other functional groups which can form hydrogen bonds.
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.
The sodium fusion test, or Lassaigne's test, is used in elemental analysis for the qualitative determination of the presence of foreign elements, namely halogens, nitrogen, and sulfur, in an organic compound. It was developed by J. L. Lassaigne. [1] The test involves heating the sample with sodium metal, "fusing" it with the sample. A variety ...
Vinyl monomers have the formula CH 2 =CHR, the most important are styrene (R = C 6 H 5), butadiene (R = CH=CH 2), and isoprene (R = C(Me)=CH 2). A second major class of monomers are acrylate esters, such as acrylonitrile, methacrylate, cyanoacrylate, and acrolein. Other vinyl monomers include vinylpyridine, vinyl sulfone, vinyl sulfoxide, vinyl ...
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.
