Procedure

The compound 2,7-di(1-cyclohex-1-enyl)fluorene can be prepared by first forming a Grignard reagent from 2,7-diiodofluorene and magnesium and bromoethane in THF by heating for several days in a Schlenk tube at about 60°-90° C. Then cyclohexanone is added. After acidic workup in hot toluene, the 2,7-dicyclohexenyl fluorene is obtained.
