Popis: Results obtained using the boron trifluoride monohydrate and triethylsilane pair are reported. The following compounds did not undergo hydrogenation: naphthalene, phenanthrene, 1-methylnaphthalene, ..beta..-naphthalenethiol, phenol, anisole, toluene, and benzene. These compounds were reduced and their reaction products were tabulated: anthracene, naphthacene, 1-hydroxynaphthalene, 2-hydroxynaphthalene, 1-methoxynaphthalene, 2-metholxynaphthalene, 1-naphthalenethiol, ..cap alpha..-tetralone, 2-acetonaphthalene, and adamantanone. Measurements were made using gas chromatography, mass spectra, and NMR. The mechanism of this kind of reaction appears to be protonation followed by hydride abstraction which is rate determining.
