Carboxylic acids effectively direct C-H activation for Rhodium(III)-catalyzed intramolecular Heck-type reactions. A catalytic amount of Cu(OAc)<sub>2</sub> is used as the external oxidant with oxygen likely acting as the terminal oxidant. Additionally, a novel electron-deficient Rh<sup>III</sup> catalyst was found to be more effective that [RhCp*Cl<sub>2</sub>]<sub>2</sub> with some substrates. A wide variety of complex dihydrobenzofurans, dihydrobenzopyrans, and other bicycles that can be easil ...[more]
