Synthesis of Isoquinolines via Rh(III)-Catalyzed C–H Activation Using Hydrazone as a New Oxidizing Directing Group

Synthesis of Phenanthridinones from N-Methoxybenzamides and Aryltriethoxysilanes through RhIII-Catalyzed C[BOND]H and N[BOND]H Bond Activation

Pd-catalyzed double C–H bond activation of diaryl ketones for the synthesis of fluorenones

An efficient synthesis of fluorenones from diaryl ketones by Pd-catalyzed oxidative cyclization is described. A possible mechanism involving a carbonyl group assisted ortho-C–H activation and cyclometalation followed by a second C–H activation to form a six-membered palladacycle and reductive elimination is proposed.

Synthesis of Phenanthrone Derivatives from sec-Alkyl Aryl Ketones and Aryl Halides via a Palladium-Catalyzed Dual C−H Bond Activation and Enolate Cyclization - Journal of the American Chemical Society (ACS Publications)

A palladium-catalyzed chelation-assisted C−H activation of alkyl aryl ketones and their reaction with aryl iodides to afford ortho-arylated products is described. For sec-alkyl aryl ketones, the catalytic reaction proceeds further to give 10,10-dialkylphenanthrone derivatives. A possible reaction mechanism involving directed dual C−H bond activation and enolate cyclization for the formation of 10,10-dialkylphenanthrone derivatives is proposed.
