A palladium-catalyzed ligand-free carbonylation reaction has been developed for the synthesis of indenones. Under CO atmosphere, this cascade reaction proceeded smoothly to provide the desired indenones in moderate to excellent yields with good functional-group compatibility. The mechanistic investigations suggested the in situ formation of palladium nanoparticles and this transformation was driven by a controlled reaction sequence of alkyne insertion followed by carbonylation and annulation to form the indenone framework.

Under redox-neutral conditions, rhodium(III)-catalyzed C-H annulation of N-tert-butyl-α-arylnitrones with internal alkynes has been realized for the synthesis of indenones under mild conditions. This reaction proceeded in moderate to high yields and with
