Rh-catalyzed C–H carbonylation of indoles under 1 atm of CO has been achieved. Various substituted indoles and indole with free N–H could be carboxylated with linear- and/or cyclic-alcohol to give the desired indole-3-carboxylates with up to 92% yield. A mechanism involving RhIII initiated C–H metallation is proposed.
