Abstract

An efficient one‐pot synthesis of indenes from simple starting materials is presented. This process involves a dual C–C bond formation through an intermolecular Heck coupling reaction followed by acid‐mediated intramolecular cyclodehydration. The strategy is amenable to various substituted aromatics to give indenes. In addition, the regioselective synthesis of benzyl styrenes in a single column purification technique through in‐situ reduction of Heck products (ketones) followed by acid mediated dehydration of crude reaction mixture is presented.
