A rhodium-catalyzed addition of arylzinc reagents to aryl alkynyl ketones for the synthesis of highly substituted indanones has been developed. The key to success has proved to be a proper choice of the reaction system, which involves the employment of dppf as a ligand and 1,2-dichloroethane as a solvent.
