1-Chloro-5-hydrindacene-1-ene (VI) has been synthesised and successfully used as a dienophile in the Diels-Alder cycloaddition reaction.It forms directly the highly substituted fluorene derivatives with fused cyclopentane ring when heated with various cyclopentadienones.During the course of reaction, both CO and HCl gas are evolved simultaneously.A few fluorene derivatives have also been prepared during testing the dienophilic character of 3-chloroindene.
