Abstract: Herein we describe an unprecedented RuII-catalyzed site-selective and regiospecific annulation of benzoic acids with propargylic carbonates. The weakly coordinating carboxylic acid moiety outperformed other typically used directing groups in C–H activation, including ketone, nitrile, sulfonamide,… read more here.
