    Hmmm..... These would seem to be substituted fluorene compounds.
    Here's a good web site.

    It's different substitutions on the 9 carbon of fluorene, but with a double bond.
    So, this is just a guess, really, but here goes in order:
    1,1-dimethyl-2-fluorenylethene
    1-cyclohexyl-2-fluorenylethene
    1-cyclopentyl-2-fluorenylethene
    1-ethyl-2-fluorenyl-1-methylethene

    There's no stereo consideration for any of them because no chiral carbons and the fluorene is symmetrical.

    There's probably a better way to do this, though.

    Look up the structures in the CRC handbook. :)

    I found a better base molecule: fluorenylidene.
    So, for the first compound, we have:
    dimethylfluorenylidene
    etc.
    But this is some tricky nomenclature, so again it's just a guess.

    I looked on chemfinder and there was nothing quite that specific... But I haven't looked at the hard copy CRC.
