An efficient synthesis of 2-substituted indene-1,3(2H)-diones from stable and readily available 1-(2-halophenyl)-1,3-diones by employing phenyl formate as a CO source has been developed. The reaction occurred via palladium-catalyzed intramolecular carbonylative annulation using K3PO4 as a base and DMSO as a solvent at 95 °C. In this protocol, the reaction showed a broad substrate scope with good to excellent yields.

Structural isomers of the monothiocarbonyl analogs of 2-benzoyl-1,3-indanedione were obtained. 1-Oxo-2-(α-hydroxybenzylidene)-3-indanethione was synthesized by the action of hydrogen sulfide on 2-benzoyl-1,3-indanedione in the presence of hydrogen chlorid
