摘要
Treatment of 1,3-propanediol-ditosylate with fluorenyllithium yields 1,3-bis(fluorenyl)propane (5). Subsequent addition of methyllithium gives the corresponding dilithio compound 6. Dilithio-1,3-bis(fluorenyl)propane (6) was treated with titanium tetrachloride to yield the organic tetrabenzodispiro[4.0.4.3]tridecatetraene product 7, presumably formed by means of a carbon-carbon coupling reaction involving substituted fluorenyl radicals. The organic compounds 5 and 7 were identified by X-ray crystal structure analyses.
