o-(Alkynyl)styrenes undergo halocarbocyclization processes via a 5-endo-dig ring closure. By this strategy an efficient synthesis of 3-halo-1H-indene derivatives has been developed.

reaction conditions. In addition, related alkoxyiodocyclization processes are described, which are particularly interesting in their intramolecular version because they allow the synthesis of heteropolycyclic structures containing the indene core. Finally, the usefulness of the prepared 3-iodoindenes has been demonstrated by the synthesis of several polysubstituted indene derivatives through conventional
