Palladium-Catalyzed Regioselective Aerobic Oxidative C—H/N—H Carbonyla-tion of Heteroarenes under Base-Free Conditions. — Using air as oxidant and a bal-loon pressure of CO, indoles, thiophenes and benzothiophenes are converted in the presence of different alcohols into carboxylic acid esters. The reaction proceeds with high regioselectivity for each type of heterocycle. — (ZHANG, H.; LIU, D.; CHEN, C.; LIU, C.; LEI*, A.; Chem. Eur.
