Here, we describe the development of a Rh-catalyzed intramolecular one-carbon homologation of unstrained aryl ketones through a formal 1,1-insertion process of olefins, enabled by temporary directing group (TDG)-aided C-C activation. The reaction provides a distinct approach to access various substituted 1-indanones. Computational mechanistic studies reveal that the formal 1,1-insertion is realized by a selective C(sp2)-C(sp3) activation and turnover limiting 2,1-insertion into the alkene, followed by a facile β-H elimination and reinsertion process.

A new method is described for the metal-free oxidation of o-vinyl diaryl ketones in the presence of molecular iodine or N-iodosuccinimide to give o-acetyl diaryl ketones. This transformation involves the initial formation of an iodohydrin, and the o-carbo
