A new method for the synthesis of indenone derivatives based on the I 2 ‐promoted cyclization of ortho ‐alkynylaryl ketones has been developed. This method provides a metal‐free and convenient route for the regioselective synthesis of indenones using ortho ‐alkynylaryl ketones with predefined substituents to give indenone products in moderate to good yields.
