An efficient one‐pot synthesis of indenes from simple starting materials is presented. This process involves a dual C–C bond formation by intermolecular Heck coupling followed by acid‐mediated intramolecular cyclodehydration. In addition, the regioselective synthesis of benzyl styrenes through in‐situ reduction of Heck products (ketones) followed by acid‐mediated dehydration is presented.

Novel metal complexes containing at least two heteroatoms attached to an indenyl or substituted indenyl radical which is bridged by ligand group thereby forming a covalent or coordinate/covalent bond to the metal, the use of such metal complexes in the formation of polymerization catalysts and processes for polymerizing &agr;-olefins using such catalysts.
