Rhodium(III)-Catalyzed Intermolecular Amidation with Azides via C(sp³)–H Functionalization

The amidation reactions of 8-methylquinolines with azides catalyzed by a cationic rhodium­(III) complex proceed efficiently to give quinolin-8-ylmethanamine derivatives in good yields via C­(sp³)–H bond activation under external oxidant-free conditions. A catalytically competent five-membered rhodacycle has been isolated and characterized, revealing a key intermediate in the catalytic cycle

Ruthenium-Catalyzed Oxidative C–H Bond Olefination of <i>N</i>-Methoxybenzamides Using an Oxidizing Directing Group

Ruthenium-catalyzed oxidative C–H bond olefination of <i>N</i>-methoxybenzamides using an oxidizing directing group with a broad substrate scope is reported. The reactions of <i>N</i>-methoxybenzamides with acrylates in MeOH and styrene (or norbornadiene) in CF₃CH₂OH afforded two types of products
