1]heptadienes thermolysis in order to generate free silylenes and the corresponding benzene derivatives are investigated. For this purpose, 29 new compounds of the types VII–X have been prepared. No indications for a polar mechanism or an intermediate biradical could be found. The degradation is exactly of first order in all cases investigated sofar, and is enhanced by phenyl groups at the bridgehead C atoms
This invention relates to 2-pentafluarasulfanylnapthalene, substituted derivatives thereof and to a process for producing naphthalene carrying an SF5 group. A 3-step process is employed wherein 1,4-dihydronaphthalene is reacted with pentafluorosulfanyl halide. Next the resulting 3-halo-2-pentafluorosulfanylnaphthalene or derivative is converted to 2-pentafluorosulfanyl-1,4-dihydronaphthalene or derivative by treatment with a base and subsequently transformed into pentafluorosultanylnaphthalene by removing hydrogen atoms.
