A cationic ruthenium(II) catalyst enabled highly efficient oxidative alkenylations of electron-rich arenes bearing removable, weakly coordinating carbamates, and allowed for cross-dehydrogenative CâH bond functionalization in an aerobic manner.

Cationic rhodium complex-catalyzed olefination of phenol derivatives for the direct introduction of an α,β-unsaturated ester appendage is described. In addition, deuterium labelling and kinetic isotope effect studies were performed to probe the reaction mechanism.
